And even if it does, who cares? What relevance would there even be to a person who can identify a brightly painted box containing a Russian speaking male person in the same room with other boxes but no other boxes containing people?
In all fairness, that's really beside the point. It doesn't matter how useless an ability is, or how weird you'd have to be to discover you have it in the first place, all that matters is that it's paranormal.
Of course, one of the really fun things about science is that many things appear to be completely useless at first, but turn out to change the world. Steam power and gunpowder, for example, were both thought useful for nothing more than little toys for thousands of years, but look what they ended up doing.
This is not to say that I think this particular case has any chance of being anything other than a performance that will never go to test because the JREF won't let through a protocol that allows tricks, but that's not the point. Whatever you think about a particular claim, that fact that the ability appears pointless is not a valid reason to dismiss it.
In the whole history of the world, I doubt that anyone has ever needed someone with that particular paranormal ability.
Do horses count as boxes? I know some guys from Troy who would find it quite handy.
