Usually when installing roms, in the instructions you're told to wipe data, and then dalvik cache.

As far as I'm aware, since dalvik cache is IN /data it's wiped when data is wiped. So why is it a separate instruction?

All stock roms and some custom roms (depends on developers) have .odex files in for all app and framework files(inside system) these are files which contains some information about those apks and jar files and these odex files are written in dalvik partition and run at the boot and make boot faster. When you install a new rom these must be wiped since it is a part of the old rom
