I'd say that's one of the only educated guess one can make at this point.

In the original secret ending, Sunset Horizons or whatever people decided to call it, this guy picks the Kingdom Key. As we learned in the first game, the Kingdom Key was meant for Riku. If this dude is the one who chose Riku, it's quite possible that the other two with him (the ones who drew the Way to Dawn and the keyblade from the world of darkness) also chose masters. Wild theories sprout from these assumptions, of course. Most of them require an insane amount of imagination, but some are fun to read when you're bored.
