Orvis bimini leader tippets ?? furled from the knot to the end loop

[Fly Goddess]

Thanks for the reply Tedshuck. I have no problem tying the bimini knot -- however the loop in the "Orvis" leader looks as if it is furled. I can't figure out how it is done. I hope I can paste a drawing to show you what I am referring to:

I would say they are "twisted". Furled is both sides twisted the same direction then when put together they furl the other. A shorb loop is needed or they will unravel.
Here is the video on how to make one:
