Yes, Mike, this is the good old "foreground anchor" carried to extremes. So much so that it does indeed appear to be two pictures, rather than one coherent composition. And I'm not at all sure that a foreground anchor works when it is not at all crisp but essentially consists of motion blur.
Technically, of course, we would have to say that it is brilliant. And others may love it . . .
