If and they are not symmetric, the above formula contradicts the variance formula, since in that case . How to resolve this?

Yikes, the expression was wrong in the case of nonsymmetric s. I have noted the symmetric requirement, and added a section showing how to derive the general expression.

Is symmetry really necessary for the expectation result?
Nothing in the usual proof of the result for expectation seems to require symmetry of :
