This is a really good point. Direct evidence of Satoshi's identity can only be in the form of someone claiming to be him, and that just wouldn't be credible. Circumstantial evidence is all we're going to get; even somebody spending Satoshi's BTC wouldn't be direct evidence since, as the article points out, someone else could have obtained (and be in the process of cracking) his hard drives.
