It'll probably need testing, but I'mma make an educated guess that this will apply whenever lifesteal would apply. It scales with critical strikes, abilities that apply on-hit effects and most physical on-hit damage; but, almost all other types of on-hit effects won't (new-Takedown and Infinite Duress are the only cases of magic damage applying life steal, I believe, so they probably will).
