I disagree, NFHS & NCAA-W says:

SITUATION 3: During an alternating-possession throw-in for Team A, thrower A1 passes the ball directly on the court where it contacts (a) A2 or (b) B2, while he/she is standing on a boundary line.

RULING: Out-of-bounds violation on (a) A2; (b) B2. The player was touched by the ball while out of bounds, thereby ending the throw-in. The alternating-possession arrow is reversed and pointed toward Team B's basket when the throw-in ends (when A2/B2 is touched by the ball). A throw-in is awarded at a spot nearest the out-of-bounds violation for (a) Team B; (b) Team A. (4-42-5; 6-4-4; 9-2-2; 9-3-2)

7-2-1 If the ball is out of bounds because of touching or being touched by a player who is on or outside a boundary line, such player causes it to go out.

2/21/12 Throw-in violations (Rule 9-5.1.b)
The interpretation of 9-5.1.b has been that when a player is standing on a boundary line or straddling
a boundary line when she catches a passed ball from a thrower-in, that player has caused the ball to be out of bounds...
