 This is intentional ... we only do automatic installs or upgrades,
not downgrades or removals.

 Of course you can do it by hand, and with the latest yum you can use
the new "distro-sync" command (but that will only downgrade if the
latest version available is older than what you have).

 If you want to force the version of a package to not change, you can
use the versionlock plugin.

 In general I'd say "don't do what you are doing, find some other way"
but then I'm not entirely sure what you are trying to do and why.
