This is like arguing about when a knot *IS* a different knot. It's a useless argument. Yes there are b's and q's there and in most methods if you look hard enough you can see them. This is A b and q method if you want to see it that way, but it's a distinct one and I don't think that's the useful element of this method.
I think it's a useful set of motions and I actually agree with Xarax in that sense. If you follow the MOTIONS you can't really mess it up, but some people do better with geometries than with motions probably. In this case you could mess it up by geometry, with the wrong tail on top or bottom (you wouldn't get a knot). I think if you tie a knot often, motion methods get easier and geometry methods don't, but I still use geometry usually at first. I can get confused about the motions someday if I don't know the geometry first.
I posted it elsewhere but the discussion correctly moved here and I'll post again, not steal Twine's thunder but just to add information for anyone looking here and show what I like:

Somewhere I found a more clear depiction of the second motion but this one is more realistic of how the motion will become with a little practice. I like to put my little finger between the standing ends to keep them from getting twisted. It helps in the second half.
