Is it not a 10% difference in THRUST. Hence if the aircraft can not calculate the thrust, due for example to damage to the various probes and sensors then TAC will not kick in initially. It MAY subsequently be available once the engine is secured as the aircraft now knows it is shut down and by definition has 10% less thrust than the other one?
