Well, no, we're both right :)

Obviously your anaconda 'repo' is not actually set up as a yum repo,
it's just a directory. So in that case, yeah, if you want to downgrade
to a specific .RPM which is not actually in one of your yum
repositories, you can specify it explicitly.

But as I said, if you have a package installed for which an older
version exists in your yum repos, just 'yum downgrade packagename' will
work.

That case is fairly common for pre-releases, because you usually have
updates-testing enabled; so any time a package is in updates-testing,
you can 'downgrade' to the version that's in the 'stable' repo, and then
as long as the updates-testing repo is enabled, you'll have an update
available.
