What does Guerilla mean? Guerilla is warfare, where you launch small surprise attacks on you enemies, so he can hardly prepare and you get the advantage. So for me the purpose of Guerilla was always only something, which boost your first strike on the enemie and not something that buff infamous exploits like: sneak - attack - sneak - attack - seak
D:OS has taught me many things, one of which is: never take things too literally. What you really care about is what it does. Heck, in this particular game, even after reading what it does, you should still take it with a grain of salt.
Just standing behind the enemie and being able to 'disappear' is just ridiculous unlogical as a concept.
Yet that is exactly how stealth typically works: as long as you're out of sight, you can "enter shadow" - whatever the heck that means. The convention is: that is a special trick only a rogue can do.
