I was there in person, but was a good 20 feet from the table at the back of the standing room only crowd.
I couldn't hear a word from the table, I was too far away.
To me, I thought I saw him point to the 2 rail pocket with his stick, but it was not super clear or obvious. Then he shot it. To me, it looked like he shot it not 2 or even 4 rail speed, but 6 rail speed. In other words, he shot it the speed for if missing 4 rails, it would go 2 more rails to get the OB away from that side of the table. The angle to me just did not look like a 2 rail angle at all, combined with the speed he hit it at. The OB looked like it hit within an inch of the corner pocket on the first short rail and then went in cleanly 2 rails. I personally think he miss hit the shot as I don't think anyone would play that shot 2 rails, where it has to hit within an inch of the corner for it to go. (Of course, I suck...., and what do I know

)
After the shot, everyone clapped, then things happened quickly. The balls were swept up. I don't recall if Shane or John or both swept them up. Then I see Shane and John talking at the table, and then Ken comes and joins them. I can't hear a word they are saying, and I don't think much of the audience can either. They are talking for a good 5 minutes it seems to me, and we, the audience, are all waiting in suspense.
Then Ken awards John the game, and said why. We couldn't hear him, so he goes to get the mic and repeats what he said. Paraphrased (but I believe to be very accurate) this is what he said: "Shane called 4 rails, the ball went 2 rails, shane disturbed all the balls afterwards, and therefore the game is awarded to John"
About an hour later, I was walking out of the tournament room, and Shane was talking to a fan that he knew. The fan asked him about a shot in the Bank Pool final. He was actually asking about another shot, but Shane misunderstood and started talking about the 2/4 rail shot. Shane said (again paraphrased, but I believe its almost verbatim of what he said to the best of my recollection):
"I called the ball 4 rails." <slight pause> "It went 2 rails" <slight pause> "Everyone started clapping" <slight pause> Then he stopped talking, and lifted his hands in the air and shook his head. That was it, then the guy informed him he was asking about another shot, and shane answered him about that other shot.
So I agree with Justin... I think Shane just had a brain fart.
I also agree with Ken's decision, since all the balls were disturbed by Shane.
The only thing I'm not sure of is if John or Shane disturbed the balls first. I didn't notice who did first. It happened fast. Maybe if John did first, they should have tried to replace them and carry on the game. But if Shane did, then for sure the loss of game was the correct call, imo.
