And when the UPS *does* get powered back on (via a button press), then the power outlet for the PC will come back on as well….  I see.  So the UPS basically has an “ignore the wall power” flag that gets set when you tell it stayoff, and for poweroff-return, it wouldn’t ignore wall power, and so would come back on when AC is restored.

Yes.

It's a little closer to what some PC BIOSes default to, where they will stay off when power comes back, if they were last commanded to turn off.
