I mean, technically if he was still alive nisovin would have inadverently helped him. He would have had to break apart the egg to get the gun out probably.
I'll have to go back to check the vod, because I'm pretty sure rob said something about how he didn't count it because the npcs wouldn't have helped, but they did. Also if it actually worked on the npcs, they would have had the same amount of time to get out as deadbones, so either he should have had until the end of their turn like they did, or they would have until the end of deadbone's turn, which would have meant they would be a lot less likely to be saved.
Also who's to say there wouldn't have been a 1 that would break the egg open on the npc's turn?
