I think Snaq is just having a brain fart.

Yep. Buried myself in the exceptions for a moment forgetting when TC ends.

Surehands, the answer to your stream of questions can be found on page 71 of this year's Fed Rules book. It has 19 other corollaries that will definitely enhance your scope of knowledge.....

13. A live-ball foul by the offense (team in control or last in control if the ball is loose) ,or the expiration of time for a quarter or extra period, causes the ball to become dead immediately, unless the ball is in flight during a try or tap for goal. The ball also becomes dead when a player-control foul occurs.

Rule 9-13-1 and pentaly says excessive swing of elbow, ball is dead innediately so the fouls by A2 would cancel A1's airborne shot.

Violations are not fouls; fouls are not violations. They are different beasts. Each has its own separate rule (rule 9 for violations, rule 10 for fouls). Each has a distinct penalty. You cannot mix and match. An excessive swinging violation by A1 would kill the shot, a foul by A1 would not.
