This works but is risky. Flies are cheaper than rods.
I prefer the roll cast method: Once you know you're hung, quit tugging. Start pulling off extra line so you can throw a roll cast beyond the snag, thus tugging the fly off the snag in the opposite direction of how it initially approached it.
If fishing downstream in current, you can also let the current form a bow in the line and then give a tug once you've got the belly way beyond the snag.
