Actually, I'm pretty sure he's right [on the mechanics at least]. The change is to make defensive dispels on others a healer only function. Spriests will only retain the ability to dispel themselves if these changes make live.
EDIT:
Dispel Magic can only be used on the casting priest as a baseline effect.Passive Disc & Holy: Absolution (new passive) enables priests to use Dispel Magic on up to 2 harmful effects on friendly targets.
