Indeed, but I don't think the A/THR was "disabled" in terms of being off or not functioning. The Asiana A/THR was inadvertently set to "HOLD" by the crew, and the Turkish A/THR went into "RETARD" (i.e. rolled back too much and too early) because of a faulty RA input. The crew moved the levers forward the first time, but did not disengage A/THR, so it simply pulled the levers back again.
