"...the teachings of Master Arca, the adventures of Jolee Bindo on the Rimward Missions. All of these things are in danger of being lost, forever."
If Jolee were alive, how would his tales be in danger of being lost?
And if Revan does fall to the dark side, Jolee actually admits to being a Jedi. Furthermore, he implied several times in K1 that he followed Revan to have one last adventure. So even if he were alive, by K3, it's unlikely that he'd do anything. And he'd be too old for that sort of thing.
