During a jump ball to start the game, jumper A1 taps the ball and jumper B1 catches the ball before the jump ball ends.

The official awards the ball to team A and sets the arrow to team A. Is the official correct?

This question is from the IAABO computer program. I got it wrong but can't find out exactly why. I remember this rule changing a few years ago but don't save all the old books in my attic.

NFHS, Team A gets the ball. Team B gets the arrow. It was changed a few years ago as it was penalizing the violating team twice.
