I see what you're trying to say, but I still can't agree with you. If you restrict your view to the area where the two levels merge, the area where the guy in the cowl, near the top of the ladder, is, all the pillars are in direct alignment with the ones immediately above them. It's only when you take a full view of both levels that the discrepancies appear, and then you see that of the two extreme pillars, at most one can be considered possible. It could be either one but it can't be both simultaneously.
