Which also basically proves he actually IS Satoshi.
it proves he made a declaration in court. this is no different than his copyright registration. i could declare that i am satoshi, and that i own the satoshi coins. does that make it true?
he even included caveats so that when he still can't access the funds in 5 months, there's a perfectly good explanation:

the more obvious explanation is that he doesn't have access to those coins at all.
