He looked at the ref because he was challenging, didnt you see the close up of it during the match
If you challenge you stop playing the point. We all know that as that decision to challenge has to be made instantly on the baseline "out" ball because it's impossible to use Hawk-eye otherwise. He didn't stop playing. There was a call of "out" from somewhere that confused everything hence the look to the umpire. I thinks that's obvious. Umpire's fault for not replaying the point.
