9-2-5
The thrower shall not carry the ball onto the court.

While the thrower is OOB, he cannot touch the floor inbounds or touch the ball while it is touvhing the floor inbounds. Even though he's touching OOB, he cannot touch inbounds nor can the ball while he's touching/holding it. This is the principle of 9-2-5.

9.2.5 SITUATION: Thrower A1 inadvertently steps through the plane of the boundary line and touches the court inbounds. A1 immediately steps back into normal out-of-bounds throw-in position. The contact with the court was during a situation: (a) with; or (b) without defensive pressure on the throw-in team.
RULING: A violation in both (a) and (b). COMMENT: Whether or not there was defensive pressure or whether or not stepping on the court was inadvertent, it is a violation and no judgment is required in making the call.
