Neutral drain function in washing machines

[Stephen Tashi]

TL;DR

Is there a animation showing how the gear case in a Whirlpool/Kenmore direct drive washer implements neutral draining?

It would be interesting to me (but not essential) to see a visual explanation of how the gear case in a Whilepool/Kenmore direct drive washer implements the neutral drain function. The neutral drain function is a period of time when the washer is pumping out water but not spinning or agitating. I've disassembled and reassembled a Kenmore direct drive gear case guided by the detailed video

I can see (first hand) how changing the direction of rotation of the shaft switches from agitation to spinning. But I don't see how it implements neutral draining. Articles on the web say that a pause in the motor rotation activates and deactivates the neutral draining. It's hard to see how a purely mechanical device can react so flexibly to pauses.
