when I first came across Zoller`s description, I was confused too.
What I think is, that he uses the words oriental/occidental in a qualitative sense. In generell, orientality means more vitality, force and also a stronger declination to socially acceptable actions or behavior. As I understand it, this is the case when the superiors are "oriental to the Sun" and the same applies to the inferiors, when they are "occidental to the Sun" - because then the inferiors take on an oriental quality and they are more efficient. This is, what Zoller is speaking about (at least in my opinion).
I hope that helps a bit.
