How come the top image can have more motion blur than the bottom one?

The pixel density is significantly higher in the center of the camera's field of view, compared to the edges

An object moving perpendicularly to the camera changes many more pixels than an object moving towards the camera

The placement of the illuminators in this scene allows more light to fall on objects placed in the center of the scene

An object moving towards the camera stays longer in the camera's field of view, allowing for focus adjustments
