Definitely similar... See Juro I'm not the only one.
There is one difference, they describe using a sidearm cast. I do it keeping a more vertical back/forward cast and using downward arm motion instead of using wrist motion to initiate underneath loop. 2 planes of movement instead of of three gives better control.. Maybe that is only true for me. I cheat to the side sometimes and situation dependent both styles have there merits, for me side arm puts me in the bushes more.
Here are the drawings I did a while back and kept forgetting to post back on this thread.
