After deknow's an off the mark reply, I did a lot more Googling and found out it was Housel Positioning he was referring to, as you point out. There are a number of discussions on this board as well. It is an interesting phenomenon. I looked at a lot of drawn comb yesterday and found it hard to recognize.
The best article I found (with diagrams) was here.
p.s. BTW, I assumed the frames were foundation-less as a lot of them Dee pulled out in the videos had comb that either, wasn't attached to the side(s) of the frame, or the bottom of the frame, as are with some of my foundation-less frames.
In the video you talk about the orientation of the foundation-less frame based on the hosel, if I heard right.
Michael Bush has some information on Housel positioning on his website.
