It was an angle-shoot. One of the commentators says that Armenian Mike made the move before and took the pot when others folded.
If Ryan folded, Mike would have gladly taken the pot. Because Ryan snap-called, Mike tried to pull this nonsense.
I understand why the floor passed it to Ryan, if Ryan is the producer for the show. It's likely there was some pre-agreement that the producer has the last word in the event of a dispute... but this was so clear, that if I were the floor, I would say:
"By the rules of poker, shoving all the chips in was clearly a bet and stands; chips cannot be pulled back from the pot. All the chips should be awarded to the caller." At that point, Ryan, as the producer, could still intervene if he wanted to. There's no need to say that out loud - all it does is put Ryan on the spot.
