Better Part of Valor Perk

[Dundalis]

Trying to get as many perks as I can in the training sections at the start of the game. Just curious with the above perk, what does the evading part of the prerequisite mean? I assume it means you cannot take down an enemy in any way, and must simply get past them (someone correct me if I'm wrong), but it says nothing about you being undetected like some other perks explicitly state such as one with the shadows.

 

For example when doing the stealth portion for Parker, do you need to get past the guards completely undetected or does it still count as evaded if they turn yellow or red but you get past them? Would like to know before I make 30+ tries attempting it.
