    Symmetry?  Could you explain what you mean?
    C-x C-o doesn't to be what you're referring to (it's bound to
    delete-blank-lines).

It is analogous to C-x 4 C-o.

The natural meaning of C-x C-o would be "display a buffer in the
selected window but don't select that window," which is sort of
self contradictory.  In fact, that meaning for C-x C-o is older
than C-x 4.
