I guess it's sort of like when you see movies of automobiles and the wheels look like they are turning backwards. Of course, they aren't really turning backwards, but because the shutter speed of the video or movie camera is different from the speed that the wheels on the vehicle are rotating, they look like the wheels are moving backward.

Very rough analogy, but I don't know how else to explain it.

Don't need a movie for that. Happens to me all the time just riding down the interstate.
