Unfortunately you twist my words here. Referring to release (!) tags,
I asked why release 3 from repo A should upgrade release 3 from repo
B?  It only does because a repo tag is included in the release tag and
becomes the most significant portion when the rest is equal. When that
happens (and not only then) we have a problem. You know my view on
repositories which upgrade eachother of overlap eachother in an
undefined way -- and I don't really wish to pound on it endlessly.

When repositories are mixed and the repo tag of multiple versions
of a package becomes the least significant part of RPM version
comparison, than that's the least important problem (but still
an issue which is beyond the scope of this thread).
