Once the tail had departed, is it clear where the loads would come from to split the fuselage at the wing box ? The inertia of the rear fuselage may not be sufficient. If so the tail must still have been attached at that point generating a force and moment opposing the wing lift, if so the tail separation was later. Ditto the HS, is the inertia of the tail alone sufficient to allow shearing by aero forces ? If not they must also have separated when the tail was still attached to the larger body.
Hardly seems necessary to point out that this is speculation......
