Hi @mschart!
While magnitude squared coherence is symmetric, the averaging across trials happens over the complex-valued coherency, which isn't symmetric -- coh(X,Y)=coh(Y,X)* [where * is complex conjugate). So if the two signals are sometimes swapped for different trials, it will change the trial average.
Does that make sense?

Fantastic, glad to read that, thanks a lot!
