It does, check your recount. You are probably not positioned in the right spot, his hitbox is really buggy. There are spots that should be in melee range which aren't, until he swings back to pick up 3 of your healers. For most of that fight, I am scrambling around looking for the spot where my auto-attacks, and not just my specials, will land. Most of the time its in front of and to the right (while facing him) of his hand, by the thumb I guess. I end up facing his armpit (not really to his hand), which is nice b/c you don't have to move to hit his chest, and it keeps you out of the adds if you tank them on the left side of the room.
