There's no magic here: the motion blur at 1/8000 is guaranteed to be half of what it would have been at 1/4000.

Actually this is not exactly correct.

True! If the motion is accelerating, the motion blur at 1/4000 will be more than twice that at 1/8000s (conversely the difference in blur for decelerating motion will be less). More to the point, what I mean is that the added 125 microsecond exposure time of 1/4000 vs 1/8000 is not likely to make any difference in motion blur for most typical situations. Given that it takes much longer than 1/4000s for the shutter to cross the entire focal plane, you'd sooner notice the effect of rolling shutter than any added motion blur. For comparison, 1/4000s would be on the order of the duration of a flash at 1/4 power (the flash would actually be longer).
