Wrong Direction
 

The teams begin the overtimelined up facing the wrong directions. The ovetime jump ball is tossed . A1 gains possession and dribbles toward what he thinks is his proper basket, crossing the divison line into what is reality is his backcourt. Team A sets up its offense, and runs a continuous motion offense play for about ten seconds before thee official stops play, and realizes what has happened.
Do you resume play with each team going the proper direction based on bench location ,give A back the ball and leave the time off the clock that has run off?

Yes. The same as if they begin the game that way.
