Breaker of Bones Ends the Turn When All Other Allies are Downed or Airborne

Title pretty much says it all. I don't recall seeing this discussed anywhere, but I might have missed it. But yeah, when the self-damage from Breaker of Bones downs iHulk, it instantly ends the turn, even tho he comes right back and seems like he should be able to make a match as well. Doesn't happen if there's still another ally standing (as opposed to downed or flying), which makes me think it's a bug.
