What do you think?

I think I have proven your hypothesis true. I created a circuit that disconnects all 4 wires on the connector and is STILL generates power. The voltage is unstable but it creates power, up to 25 amps of power at 12-13v. I used a ~70amp load tester with the alternator circuit disconnected after engine start. I was very surprised. That connection to power internal to the alternator is keeping the regulator running, as you thought.
I'll post some details in a few.
