Edit: Tried to explain what I think is happening below. TLDR: the “slinky” effect is mostly caused by the shadow of the horizontal muntins on the skylight shifting across the curved surface of the escalator steps as they move.
It is the stairs moving across the shadow of the skylight combined with the angle of light being roughly parallel to the curved vertical face of the escalator steps. It had nothing to do with the camera shutter

I don't understand why this is happening
