"When A1, in making the throw-in, reaches through the end-line plane into the playing court and B1 slaps the ball from the hands of A1, without B1 breaking the plane above the end line, B1 has not committed a violation because the ball is in play once it crosses the end line."

Is this also true in NFHS? Once the ball is held over the end line it is fair game, (except in the case of a smaller court where there is not enough space behind the inbounder)?
