Just want to add my two cents.
Bishop may have given up on the play because he thought that the play was over. In his mind, maybe he felt the puck hit his pad when it was actually Trocheck's stick. (I am guessing...this would be my thinking in his position).
Second, in my opinion, any stoppage or reversal of the pucks forward motion toward the goal line should cause the play to be blown dead. Yes, this includes dekes that pull it back, or loading the stick for the shot. But these are not that big a deal, and they make for great replays, so I am not too concerned with them.
I do question if this was a clean miss on the shot attempt, though. The still frames seem to show that the backhand move to pull the puck back to forehand and load the stick had the puck moving away from the goal line. This is allowed by current convention. But when the puck goes off on its own, it is moving toward the goal line again, however slightly. This implies contact with the stick. And I do not think anyone argues that it was not a true shot attempt. Therefore, if it was a shot attempt, and contact was made with the puck, however slight, that imparted motion in the direction of the goal line, does it not count as a shot...even though it was well wide and very slow? That is a weak argument to overturn a call, but it should be good enough to keep a call from being overturned as this was.
A stronger argument is that he stopped the puck with the tip of his stick (as in tip of the toe, blade was vertical). It appears this actually pushes the puck away from the goal line, but the overhead is not wide enough to see it for sure (one angle does show it in relation to the top of the netting from an end loge camera). He then repositions himself and his stick and fires the puck into the net. The movement of the puck backwards was not part of a deke. It was to stop the puck from moving to a worse angle while he got in place to shoot. Also helped to improve the angle very slightly. This part I see as against the spirit of the interpretation that allows dekes. It was not a single move that he was in control. It was a stop and move it back, then a shot.
