Considering only the loops, I think it's actually the same topology, just with two loops instead of one. Assuming I understood the end of the video correctly :-

Considering only the loops, I think it's actually the same topology, just with two loops instead of one. Assuming I understood the end of the video correctly :-) I think it's also required that the two loops be the same circumference, unless something really tricky is happening with the fabric to allow them to be coiled concentrically but with different centers.
