I've tried it and it works.. sometimes.
The best thing I've found to do is to keep your thumb tight on the spool as you pull the line out, and when you get to a snag, pull the line that forms the loop (while keeping your thumb on the spool, keeping your thumb on the spool prevents more line from running underneath the mess you have on top).
Just use both techniques in unison, but use the video technique last - I've had it screw me up more than help most times... I need to give him one of my "professional overruns" to play that technique on and see how well he does it..
