How is it easier for oil to foam when the air mixed
with the oil is being "sucked out" by lower pressure
in the crankcase?

I don't believe any mention was made about the boiling
point of the various fractions of the oil, and
frankly, I would think that faster evaporation of the
unburned fuel in the oil would be an advantage in
lubrication, not a disadvantage.
