Neat! I have confirmed your observation about the relative positions of the two feet being different in the two directions.
It’s pretty subtle though—the “right cue variant” in the show/hide box here (direct links: left, right) doesn’t look obviously “from below” to my eyes. Maybe a bit? Hard to say.
So your clockwise model is actually more veridical
I disagree with this part: I would say “So your clockwise model actually has a stronger prior”.
As I wrote: “A veridical model of the real-world thing you’re looking at would feel like a 2D pattern of changing pixels on a flat screen—after all, nothing in the real world of atoms is rotating in 3D!”
Schröder’s stairs likewise has the property that one of the options tends to be stronger-prior than the other. (Most stairs are on the floor not ceiling.)

Fair enough, if this silhouette was actually generated from a mathematical 3D model rather than a real dancer, as I assume it was!
