Schneier is one of a fairly limited set people in the world who has the technical skills and background to be Satoshi, so it's not a completely ridiculous assertion. However, virtually nothing else about Schneier and Satoshi lines up, Schneier being a notable crypto skeptic and having distinctive writing style quite unlike Satoshi's. Nevertheless, he's prominent enough that it makes sense to forcefully deny the rumor, just to make it less likely that he'll be targeted by kidnappers, cranks, etc.
