Well I think he meant what I think he meant. When you die and go to village yes, you get full HP and CP, but after you buff again you have something like 70% more HP with the buffs, which doesn't regenerate on the spot. So you have to wait to use GHP and Elixirs of Life until you get back to full HP before you can go PvP.
This is probably not the best explanation, but I hope you can understand what I'm trying to say.
