That flip transfers angular momentum to the domain wall, pushing it along in the direction of the current.

Proof of the feat was published in Nature Photonics, which details their use of orbital angular momentum (OAM) to make the magic happen.

This is because of conservation of angular momentum, the same property that causes ice skaters to spin faster if they draw their arms in.

Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above.
