Seems like they could be correct:

NBA Rule 10

Section III—Thrower-in
A thrower-in shall not (1) carry the ball onto the court; (2) fail to release the ball within
5 seconds; (3) touch it on the court before it has touched another player; (4) leave the designated
throw-in spot; (5) throw the ball so that it enters the basket before touching anyone on
the court; (6) step on the court over the boundary line before the ball is released; (7) cause
the ball to go out-of-bounds without being touched by a player in the game; (8) leave the
playing surface to gain an advantage on a throw-in; (9) hand the ball to a player on the court.
