Still doesn't fully compute for me - practically the roll moment applied if weighting the outer pedal more should be practically less if the pedal/crank is lower from raw geometry, but I think this is a more complex interaction.
I think the ultimate answer has to do with the timing and weighting of initiating corners, and to a limited extent how much height differential between feet actually happens.
I find that even trying to replicate Nicolas Vouilloz with really dropping the outer foot, I actually end up with my feet roughly level on anything but flat/off-camber, which makes me prefer the lower BB. In those longer/flatter turns I do feel like the lower BB is just letting me push the back end into a slide as needed, so technique is a big part of that decision. The other bit is the dynamic weighting - when I'm really on it I'm basically pumping my fat self to change direction with real authority, but I can get away with this on a carbon 127mm rear travel setup quite easily, whereas on Aston's bike, that is an inherently more cumbersome process, so having more BB height isn't a detriment to cornering, so might as well avoid clipping rocks.
For my part, the really low BB, 175mm cranks, and my lack of talents results in my chewing up rubber crankarm boots at the rate of one set per season, but I can print more out of TPU whenever I want (or buy more), my pedals look I've been trying to tie them to the bottom of my boots and use them as crampons, but overall that's the handling I've found works best for when I'm actually going fast, and I'm pathetic at technical climbing once tired anyway.
