It's another example of inconsistent writing sadly.


 * Vrythur says: "The moment I was infected by one of my own Initiates, Auri-El turned his back on me." 
 * Gelebor Says: "I don't understand what he's become, but he's no longer the brother I once knew. It was the Betrayed... they did something to him"

Maybe he became a vampire long ago but kept it hidden and acted normal - He was the Arch Curate after all and why would he want to risk his lofty position. Then when the Falmer attacked it triggered something in him and he changed and Gelebor noticed it.
