My laymen’s interpretation is that superconductors perfectly expel the magnetic field without distorting the field and so can sit in a position that is effectively locked and held in position. I could be completely wrong however.

There's a noticeable distortion of the magnetic field near the superconductor. It's this distortion that keeps the superconductor stable - it's caused currents that appear on the surface which match and cancel* the surrounding field.

*some of the magnetic field penetrates onto the surface of the superconductor, but internally, there's 0 magnetic field within the superconductor.
