They're not "alternating" two different pieces of music, though. There's one piece of music, and one player is playing it forwards while the other is playing it backwards.

If the video wasn't insisting on "printing" unrelated moments in the music on the strip on both sides*, you could simply take its Möbius strip apart into one non-twisted loop that's twice as long. You'd still have the thing with the two cursors going around in opposite directions, and that's what would provide the structure of the music.

\* actual mathematical mobius strips do not have two sides, not even locally, that's just what you get when you make them physical objects in 3D space
