can a teammate of the thrower reach across the throw in plane?

[rsl]

Apologies for the trivial issue, but it is on the test. Just finished my test, and I disagree with an answer. What think ye?

The throw-in boundary plane is in force only for the opponent(s) of the thrower.

According to 7.6.4, "The opponent(s) of the thrower shall not have any part of his/her person through the inbounds side of the throw-in boundary plane until the ball has been released on a throw-in pass."

According to 9.2.3, "The thrown ball shall not be touched by a teammate of the thrower while the ball is on the out-of-bounds side of the throw-in boundary-line plane"

My strict reading of these two rules says a teammate of the thrower can legally reach through the boundary plane as long as he doesn't touch the ball, and the correct answer is true.

Apparently NFHS disagrees with my reading.
