The idea of those (i.e. like this
https://www.youtube.com/watch?v=AWojYBhvfjM&vl=en) is that they're an example of equi-potential behavior.
The superconductor can move because it's staying at a consistent height.
The video linked is also pretty good at showing similar behaviors to the sample of LK99 we see claimed in the video: the superconductor can wobble, shake and does return to it's original position (or tries to) - but it's got a lot more mass.
