How is that list generated?

I'm not aware of any tight coupling between address assignment and AS  
assignment that binds anybody to advertise particular routes with  
particular origins, at least at the time that either is assigned/ 
allocated by an RIR/LIR.

Without such a coupling, would a report along the lines that you  
suggest implicate the advertisement, or the "whois record" (whatever  
that means)?
