Ah, thanks, I see what happened. It's because I have a 90 degree rotation about Y in the Input GameObjects properties. The GameObject stretches along the spline when I scale it in X, but the spots only move when I scale it in Z because they always use the gameobject's pre-rotation bounds.
This also affects Deform Mesh, so I will need to modify the input bounds based on the rotation in either case.
