This is what I would expect, since the first boot after preupgrade is run on the older system is to anaconda in upgrade mode; that never ran, you've only downloaded all the pieces necessary to do the upgrade (pieces meaning the installer image with anaconda, the new boot, and all the rpm's necessary for your upgrade).  That first reboot into anaconda does the upgrade itself.  Do not trust the progress bar in an upgrade, incidentally.

It appears that the grub entry to boot into the installer (anaconda) in upgrade mode isn't there, and thus it won't boot to it and thus won't upgrade.  It's primed to boot to it, it just hasn't yet.
