Ward Against Death (Repose Domain Ability) removes the effect of negative levels while a creature is inside the Ward. So a creature with 4 negative levels would have their maximum hit points increased back to full (gain of 20hp).
I have a few questions I'm hoping someone can help me with:
1) If a creature's maximum hit points go up, do their current hit points also go up? So if Allen is at 50/80 hp with 4 negative levels, when he enters the warded area will he be at A) 70/100 hp or B) 50/100?
2) If B, what about when he leaves the Ward/the effect ends? Does he lose 20 hp because his maximum hit points decreased by 20 putting him at 30/80?
3) WAD does mention what kind of action it is, does that mean it is a Standard Action to turn it On/Off? I feel like I read somewhere that Supernatural abilities are assumed to be standard actions unless mentioned otherwise, but I can't find it in the rules.
I should note that both RAW and RAI answers are useful as this is for a home game, not PFS.

Ward Against Death (Su): At 8th level, you can emit a 30-foot aura that wards against death for a number of rounds per day equal to your cleric level. Living creatures in this area are immune to all death effects, energy drain, and effects that cause negative levels. This ward does not remove negative levels that a creature has already gained, but the negative levels have no effect while the creature is inside the warded area. These rounds do not need to be consecutive.
For each negative level a creature has, [...] In addition, the creature reduces its current and total hit points by 5 for each negative level it possesses.
