"Infinite vitaity" more or less refers to how zombies just don't get tired (this is explored in the dragon zombie profile), but nonethless they are still going to be disabled in a fight if you wound them badly enough.

And regeneration is a stock ability for all the undead (or at least the ones that were once other beings), as them regenerating their decayed/damaged bodies through sex is the norm for them. The ochimusa is just notable in that she is more likely than most to end up with serious wounds after becoming undead, and thus needing extra healing.
