I don't see it as coincidence, how it's speed appears directly proportional to the cameras movement from the original focal point and that it moves in the same direction as the camera, most noticeable at the end, when the camera view shoots upwards.
Also, you can see two other light sources in the shot that follow the same pattern.
Really, who believes this crap?

Another website actually had a huge discussion on this. Bunch of idiots can't tell that it's a reflection.
