Well healing heals. Undead have a certain magic that can be destroyed by healing. The healing is not doing that on purpose it is simply trying to heal the victum which the healing doesn't know its dead already. Soulblighter didn't escape the healing's full force or learned to repel its affects. He is just not an undead.... he doesn't have that magic undead do. We are not giving much information about his past, but we are told he did manipulate himself to be immortal or try to be immortal. In TFL Bungie might have made Soulblighter leave after healing as an easter egg or a shortcut or maybe to give players a chance or whatever. It would be too simple if a Fallen Lord could be defeated by healing it.
