The answer to your question is: yes and no. It has a genus if you conceive
it with thickness. But to resemble a Moebius strip you must give it a total
twist of 180 degree and this infeasible with Linde's closed sweeps.
For threads, your approach is perfect. Linde's sweep.scad is useless unless
you control twists and initial angle. And, of course, it is not closed.
