It's not a trick, it's a technique, it's called "trapping", and snipers are taught the technique as well. You can either "trap" or "track" your target. (I suspect that "trap shooting" get's it's name because that's the technique involved, but i'm not really into any shotgun sports, so i cannot say for sure).

Trapping involves aiming at a point in space, and firing at said point so that your bullet and the target intersect at the same point in time.

Tracking involves aiming just ahead of your target as it moves, swinging your weapon along as the target moves, and firing when you're ready. I find tracking to be much more difficult, but that's just my opinion.

At any rate, it's not a trick.

There is very little question in my mind that Munden could easily trap a fellas' noggin' at a typical gunfight range if the target were moving full speed laterally.

This guy probably expends more rounds in one day than 99% of us expend in a year.
