AT rotor spinning when winding with crown

It creates a hydraulic connection between gears and plates rather than an actual mechanical connection.

Similar to my thoughts.
Conjecture …
As the 8800 use a dry ceramic rotor bearing then theres very little (if any) startup inertia required to get the rotor to move . (Very low stiction in the bearing) Any drag imposed by a hydraulic connection is transferred to the rotor mechanism but as theres very little resistance the rotor starts to spin.
Thats just guesswork on my part.
