All responses are correct, but I will add for clarity that THE PLAYERS in soccer may go out of bounds and play the ball as long as some part of the ball remains inside the boundary plane. So THE PLAYERS can leave the field through the normal course of play in soccer as well as in basketball.

He could have been incorrectly interpreting the violation for leaving the floor (going out of bounds) voluntarily.
He is wrong because a player may have his/her momentum cause him/her to go out of bounds while making a play, and that is NOT to be penalized as a violation of the rule.
