Even with PRH you can apply orthogonal matrices to intermediate vectors to generate different weights with similar effects.

Even if a slight rotation passing through a nonlinearity isn't good enough, you can just reorder the vector components which makes literally no difference.

Representational similarity analysis is concerned with representation structure independent from the coordinate system it sits in. A map rotated 45 degrees is still the same map.

A "reorder the vector components" transform preserves the similarity perfectly. So does a transform that maintains orthogonal equivalence.
