Either the tutorial was completely written wrong, or you read them wrong. There's no way of telling which happened, but the point is to be very careful with fastboot.
The command "fastboot flash boot file.img" doesn't flash recovery in your boot partition unless you mis-labeled your .img file and flashed the wrong file in the wrong place.
Most people modding their phones are going to be using fasboot to flash to boot, recovery, system, or bootloader. It's important to understand all of the places that fastboot can flash before you start pushing in .img files. Understanding fastboot commands can also help you possibly identify if someone made a typo in their guides.
Want to put in recovery? "fastboot flash recovery recovery.img". Want to put in a new kernel? "fastboot flash boot boot.img", and so on. Ensure that you've got files that are properly named and you won't ever have to worry about flashing the wrong thing in the wrong place.
