One of a series of statements I found in the article related to what I wrote above: "Li wrote a model that used price rather than real-world default data as a shortcut (making an implicit assumption that financial markets in general, and CDS markets in particular, can price default risk correctly)." That's the kind of assumption which, if everyone makes it, leads to disastrous results (as evidently it did).
in case it's not clear
