Not sure.
In any case I suppose it would be simple to crete such an identity relation.

It does indeed imply that, though you can't write it out like that
in most serialisations, other than N3.
And being able to write it out, makes it easy to explain what symmetry means.
I think people keep confusing syntax and semantics for some reason, even on
the semantic web.
