yes, but all 3 scorers could still go back and start attacking in defending teams half if they turn quick
So? If all three players rushed back to their offensive side they'd be leaving their goal unattended and the other team in possession of the ball. One long shot and you're done. Even if it goes wide the team who had the ball would all be pointing the right direction whilst the 3 from the other team would still be rushing the wrong way down the court.

You're arguing a point which just won't happen.
