Yeah, I don't know about the author, but my brain spatial memory is very much tied to Euclidean geometry. The holonomy effect (view is rotated when coming back to the same point) in particular is very disorienting.

It's cool, but I would never use this for real.

I think it means you remember things by where they are relative to each other.

But yeah, the rotation effect makes it a bit confusing compared to normal space.
