The Emperors ruling from Cyrodiil were Dragonborn (blessed by Akatosh through his covenant with St. Alessia in the First Era), not the High Kings of Skyrim, and that ended with the Oblivion Crisis, around two hundred years before Ulfric slew Torygg (as the events of Oblivion mark the transition from the Third Era into the Fourth).

As shown by Pelagius "The Mad" Septim, there were those who held both titles at least during the Third Era, but the title of Skyrim's High King is not involved with Akatosh's Dragonborn covenant.
