Will have to disagree here. I have had one engine stop while doing an EOL for a PC in a 300 as it happens ( customers aircraft ). Throttle was rolled back into detent and engine stopped. I can assure you that the ac descended considerably quicker than a normal auto followed by EOL. Having done thousands of EOL's to the ground I speak with total assurance. Quite why, that is is interesting, as you say there is a freewheel disconnect !
