Throw in situation:

That is true. But as I stated above, if A1 never releases the ball, then the throw-in has not yet ended and he may still pass the ball directly into the court before the five second count expires. Thus not violating 9-2-2.

Touching or grasping, it's no different.

I agree. Both are legal.

As for your emphasizing the part about opponent may touch the ball, I already answered this. But just to be complete I'll add to what I wrote earlier:
A rule granting permission for a player (opponent or teammate) to do something, does not automatically proscribe another player from this action.
We agree that the opponent may touch or grasp the ball in this situation and that the note under article 11 specifies this. Where we disagree is that I say that there is no rule which says that a teammate may not also do just this. You claim that 9-2-2 covers this. That is clearly not correct, since A1 may fulfill this requirement at anytime before the throw-in ends.
For example, A1 may throw the ball straight up in the air, catch it after it comes down, and then throw a pass directly into the court which touches another player without violating as long as the pass was made before the 5 second count expired.
The simple fact is that there is no rule which prevents A2 from contacting the ball or the thrower during the throw-in.
