is it not clearing cash and doing a factory wipe? does it mean just to flash the zip over the last rom flashed and doing nothing else?
Yes dirty flashing means flashing without clearing anything out.
A clean wipe is wiping cache, dalvik cache, doing a factory reset and wiping system.

Thank you. In clockworkmod recovery wiping cashe and factory reset are in the same function right? I don't have to do three different actions, just two (reset dalvik, and reset cash+factory wipe is one action that does two things) right?

Yes and then make sure to format /system as that is where the old ROM is installed at.
Performing a factory reset wipes /cache and the dalvik cache as well, so you don't need to wipe those and then perform a factory reset, or the other way around. Doing so is really just wasting time. The same with wiping system before flashing a ROM. If the ROM isn't already doing this as part of the flash process, IMO, you shouldn't use it. If you can't setup the updater-script properly, who knows what else isn't right in the ROM.
See, believe what you want, but there are still people who believe in wiping 3+ times.
Never hurts to make sure everything wipes correctly. Specially when you have recoveries that don't work right. Plus clockwork mod is well known for having issues with wiping. Maybe not on this phone, but in the past. I refuse to use it. Even TWRP for this phone the latest version is goofy.
Better to play it safe.

Well not exactly true; I don't think anyone wants the residue after a poop; but plenty of folks would like the residue data (contacts et all) after a flash
if you look at it that way yes, but thats not my point. dirty flashing is ok when upgrading from lets say beans build 7 to build 8, long as the base has not changed. other than that a full wipe is recomended when flashing or your device might develop a stinch and discomfort, causing force closes. apps and contacts can easily be backed up with google or tibu, so there is no reason not to wipe before changing roms.
What exactly is considered the same base? The kernel version or something else? I.e, lets take cleanrom as an example (which is what I currently use). If we look at the files in cleanrom (via unzip -l) at what point can we determine that the 'base' has changed ?
(I understand your point; it still myths me that different versions use different file structures for caches/data; I mean I understand how it could happen but for some reason I thought he root branches were all the same for android which would imply the data files/format would be largely the same; pity there is not some sort of auto versoning of the data on disk so that when the app loads it if the version was inappropriate it could just kick it out).

You mean this line:
International N7105XXDMA8 Jellybean 4.1.2 Base
or this line
Rebuilt: Complete rebuild from N7105XXDMA8 International Base!
--
4.2.5 is from:
Rebuild: Complete rebuild off the international N7105XXDLL4 Base
but also
International N7105XXDLL7 Jellybean 4.1.2

So would that imply that 4.5 and 4.2.5 have different bases or same base (since they are both off of 4.1.2) ?
Yes they would be different bases since they have different build numbers. There will be a lot of revisions on the same Android version (in this case 4.1.2) however it is recommend to clean flash in the different builds even if Android version stays the same.
I'll add that I personally always clean flash. With a good backup app, I use titanium backup pro, it literally takes less then 10 minutes to be fully back up after a flash

Yes but on Scott board he suggest you should not restore apps from TB backup:

Very confusing.
agreed! thats why guide simply states to wipe data then flash rom...no extra bs is required. in my gs3 guide i do infact have instructions stating to wipe system but that was just to make a few folks happy that kept insisting it was needed. either way it does no harm, so yea.Formatting multiple times to make sure it formatted properly? If you go to clean install the OS on your computer, do you format the HDD 3 times as well? Same principle, different device. If it doesn't format properly the first time, what makes you think doing it again will format it? If it doesn't format properly, it's going to give you an error in recovery, and trust me, recovery will complain when there is a problem, even if it is a minor one. Feel free to continue formatting /system before flashing a ROM, and wiping everything 20 times, but I'm trying to prevent people from wasting their time and continuing with the mis-information of needing to "wipe 3 times"
