I find that the "Complex Motion Example" in the motion layout did make a small mistake.
When the header is expanded, you can drag down the header. Then the header will shift from start contraintSet back to the end constraintSet. When I remove the onSwipe of the background image in the header 's motion scene. The bug disappears.
