As explained by BEA, the center and rear attachments of the V/S failed under vertical inertia loads which pushed the V/S into the fuselage.
Are you sure that was what the BEA concluded? The following quote is from the first interim report released by the BEA. Did they later come to some other opinion?
The tail fin was damaged during its recovery and transport but the photographs available made it possible to identify the damage that was not the result of the accident. The middle and rear fasteners with the related fragments of
the fuselage hoop frames were present in the fin base. The distortions of the
frames showed that they broke during a forward motion with a slight twisting
component towards the left.
It looks like you are confirming their view of how the VS separated.
