This last difference being due to the size and shape of the camera, with that part highest on the post rotating more than the far side which essentially just slid out laterally with very little rotation. The final little wobble in the trail indicates that the camera shuddered a little in the last few instances of the movement. And the brighter stars show a little jolt in their final shape as the camera thumps in its final resting spot.

If only astrophysicists could reverse engineer the time line of the universe so eloquently Alex. Makes sense.
