Until I see a screenshot from a better source, this is complete hogwash. I would have revealed this first, because it’s possible to fake an iTunes version string through Xcode; creating something like this would’ve been a bit more difficult, but it doesn’t matter. The entire build that was received is fake, and if any other sources call it “credible”, I find that very hard to believe.
I have no knowledge of this one way or the other, but Clayton seems pretty sure of himself.
