Given Horace's figures, combined with your observation here above, it would seem that there is likely to be some combination which could result in the current configuration. BTW in the close up, the "wall" appears to split into 3 lines (or mountain ranges) deep in the shadow portion. This may be an indication that the bodies were rotating relative to one another (highly likely anyway) at the time of impact.
