Huh????????

Excuse me for a moment, my brain just fell outta my head.

watched it 6x and still can't wrap my head around it.. Wait.. ok, i got it. Stop reading now if you don't want to know the trick.

Someone off-camera is rotating both wires depending on which one he pretends to pull, while he is sliding his fingers along the part nearest the paper, so he follows the same 'groove' during its rotation while appearing to pull. At least, that's how i THINK it was managed. The only part that bugs me about my theory is not seeing shadows or anything else, while apparently seeing at least the rt edge.. idfk. Maybe I'm way off, lol. Either way though, impressive effect. I like.

Look at the slight discoloration of the direct background of the spirals compared to the full background and the small white markings on the midpoints. Each coil is connected to a sleeve behind the other. When one coil is pulled it's coming out of the sleeve behind the other. The small white markings are where tiny paper strips provide for the pull. Check the first 'pull' where movement of the endpoint is more apparent.

My guess:
The two twisted wires are in fact bonded together (the 5cm that seems to overlap in the middle).
The trick would be to move one hand and let one end of the coil slide/rotate between your fingers while your other hand stays still and also let the coil rotate. It should give the illusion of a movement of translation but it's only a rotation that's happening.

Yep - #5 wins the "how's it done" prize

My head hurts

Here's the explanation:

Mea maxima culpa. Nice call, Malakyte. I was so sure.
