The way I was taught was to whistle on the horn, that way 'all' can tell where the ball is in relation to the horn going off. In this case, ball is in flight, whistle sounds, easily determined that the shot got off before the horn, and will be good if it goes (as long as it doesn't hit any basket supports).

You were taught incorrectly.

The whistle is to be blown to signify that the ball is dead or that a foul or violation occurred during the try. Therefore, if there isn't a foul or violation (such as the ball hitting something OOB such as a backboard support ) during the try, it should be blown as soon as the try is over--it is clear that it is unsuccessful or after it is successful.

Remember the sounding of the horn doesn't end the quarter or make the ball become dead when there is a try in flight. So you don't blow the whistle for no reason during a live ball.
