Peeling of fuselage skin by wind aerodynamic forces works from front to back. Not from RPB toward cockpit.
Also, with ruptured rear pressure bulkhead, damage pattern aft of RPB should be different, as you could imagine how all that aft galley stuff was pressed through rapidly emerging hole.
I do not think you can be so certain. The horizontal stabilizer is not with the rest of the wreckage. Therefore it departed the aircraft before it reached low altitudes. If the horizontal stabilizer departs an aircraft it will (usually) bunt hard several negative g it will then start tumbling and what was the rear of the broken fuselage becomes the leading part of the fuselage into the slipstream it would be unaerodynamically shaped and could be expected to start breaking up as the direction became more vertical. This would put all the major parts of the wreckage in one area and some parts like the HS in a completely different area. Precisely what is seen in this incident. This could also explain some of the injuries.
If memory serves correctly, the Indonesian A320 crash resulted in similar fragments of the aircraft with a similar dispersion.
