It doesn't say that at all. You are implying that it is legal for a player to touch the ball anywhere IB or OOB during a throw-in

You guys are reading way too much into this.

7.6.1 - Only describes what makes a legal throw-in, it does not address the issue of what to do if a player who touches it is OOB.

9.2.2 - says the same thing.

9.2.10 - Is the only place where we have a violation. The actions of the thrower were legal as described in 7.6.1 and 9.2.2.

The only place anything is described clearly is 9.2.10:
"No player shall be out of bounds when he/she touches or is touched by the ball after it has been released on a throw-in pass."

And it tells you specifically what to do about it.
Ball to opponents for a throw-in at the original throw-in spot.

7.6.1 & 9.2.2 tell you what can happen. 9.2.10 tells you what to do if it does happen, not the other way around.
