Uh, yes he did. Akatosh specifically made the line of the Dragonborn because Alduin rebelled, the line of Dragonborn emperors were made to show that one day the Dragonborn would be needed for this one and only purpose as well as to seal off Nirn. That's kind of the entire story of Skyrim. And Akatosh and Alduin are the two sides of the same coin. Alduin is an aspect of Akatosh in Dragon form, but that does not stop Alduin from being the first Dragon and the oldest living thing on Nirn.
