I don't know... The game makes a pretty big point out of Revan being known for wearing a mask - that's why even Juhani doesn't recognize Revan in spite of having been saved on Taris by Revan and then come to see Revan as a hero.
So it seems pretty clear to me that Revan used to wear the mask even before he was cast out of the jedi order and fell to the dark side. He even wears the mask in the cutscene where he and Malak find the Star Map on Dantooine. And they definitely haven't fallen at this point, since Malak makes a big issue out of how they can never go back to the jedi order, if they use the Star Map.
