Not really. But I didn't see it describe any alternative paths either.

That we do. I'm now seeing it more consistently. Perhaps I used too
high a battery voltage in my earlier experiments, so I only hovered
around Vth(sysok) = 3.1V (*), but didn't reach Vth(batok) = 2.8V.

(*) Set by u-boot. NoPower defaults are different.

Also, Sean McNeils experiment confirms these findings.
