you didnt answer the question, and I think you are making an invalid assumption.
Hand editting /etc/fedora-release is not sufficient.

man yum.conf
$releasever
              This will be replaced with the value of the version of the pack-
              age  listed in distroverpkg. This defaults to the version of the
              package redhat-release

yum does not read the string in /etc/fedora-release, yum queries the
rpmdb and asks what the version of fedora-release package that you
have installed from the rpm database.
