If you’ve just gone through and done the install of the patch, you may have noticed that Blizzard showed you patch notes that were very poorly updated and contained some really, really, really outdated information.
It’s just a mistake.
Circle of Healing won’t have a cooldown. It’s called “Twin Disciplines” not “Twin Faiths” and it only works on instant-cast and some channeled spells, not all spells. Improved Spirit Tap won’t give you a 100% spirit bonus … and the list goes on…
Keep an eye on MMO Champion. They’ll have the actual patch notes up as soonish, I’m sure.
