Correct - the tail always exerts a down force to balance the c of g and the centre of pressure on the wings. (Speed Stability)

At high angle of attack, once the wing was stalled, airflow from that wing had less down wash and a more turbulent flow from the top of the wing, which destroyed the "lift" from the elevator of the T Tail which now sat inside that disturbed airflow.

The rear mounted heavy engines means there is a longer fuselage forward of the wing than behind, which hinders a natural recovery.
