Wrong Way! Wrong Goal?

[Rick Durkee]

At the start of the second half, the teams play in the wrong direction. None of the officials, players, or coaches recognize the problem. After a couple of minutes elapse and teams make a couple of goals, somebody informs the players on Team A that they are going the wrong way. A1, who is near the goal that should be have been hers had the teams played the correct direction, tosses that ball into that basket. The officials now stop play.

Rule 4-5-4 implies that the last goal scored by A1 should be counted for team B. Does that sound correct?

Second, if an official hears the person inform team A players they are going the wrong way, should he/she stop the game to prevent A1 from throwing the ball into the "wrong goal"? Or, should the official allow the player to finish the play before stopping the game?
