My interpretation of the above (when thrower in touches legally positioned defensive player) would be a throw in violation for failure to throw the ball directly into the court.

The defense knocks it out? Where does it go? If it goes in bounds, play on. If it goes out of bounds, give the ball back to A (assuming B was the last to touch.)
