The comet-tail effect is a result of two exposure lengths, one short and sharp, one longer and more blurred.
Every motion camera ever made has "motion artifacts". Nothing reproduces exactly like we see. Some "artifacts" look better than others. Some we have gotten used to. "Magic Motion" and "MNMB" just create different types of motion artifacts... or motion "looks". There are limits to motion with every camera. HDRx™ and these two flavors of motion have their own different limits. Learn what they do and use them when they give you what you want. Turn them off when you don't get what you want.

Assuming I am interpreting Jim's words correctly the "quick" X frame is read out during the time the longer base A frame is being read. Perhaps they start reading at the same time but the X "quick" frame finishes it's read sooner. Perhaps the X "quick" frame starts reading later then ends at the same time as the A frame. Perhaps it happens in the middle of the exposure time of the A frame.
Based on some characteristics of the Vegas sample footy the best current guess is that the X frame starts reading later in time than when the A frame starts reading but they both conclude their reads at the same time. In any case, it will be fun to watch this tech mature. While certain instances may "break" the illusion, I expect Graeme and the Foundry and others in the future to come up with very advanced ways to recombine the two frames to cover virtually any situation.
The more interesting aspect of this to me is something Jim has mentioned several times, what is the real world human visual experience of seeing fast moving things (or spinning your head quickly). When I wave my hand quickly what do I see? You can test this yourself without an EPIC assuming you have reasonably good normal (that's a thread in itself) vision. Obviously there is a whole debate about what we are conditioned to when watching movies or TV vs real world.
Here's to 48fps base frame rate, HDR, 4K measured resolution after decode imagery and the future - Cheers!
i called it .. i knew secret #21 was hdr look it up the post is still there muahaha evil genius strikes again
but i digress
