i think you could make this with tunisian. when it gets the the split, you could keep working half the stitches until both halves are long enough and then start stitching across the entire piece again at the other end.
There is no mystery to this gorgeous wrap, just a simple twist. You work it as a rectangle, then create a Möbius strip by rotating one end 180 degrees before joining it to the other end. Also has video on Tunisian Crochet hook and stitches
