What is missing?

This happened the other night would love some thoughts.
2 person crew. Lead blows the whistle, indicating a foul on the baseline. A1 and B1 fly out of bounds, official moves to avoid them. It takes a few seconds for one of the players gets up. In the mean time the Trail is coming down to keep order and rotate to the spot. The lead,then goes opposite table, becomes trail and the ball is put in play.
