So far as I understand it's a lot more than that. Their model has not only indexed but has also individually classified 900M+ citation statements by sentiment, the outputs of which produce a score to represent each paper's relative trustworthiness.
To your point though it's fun to think about generative applications too. I for one would appreciate a writing assistant trained on millions of scientific papers -- like OK I'll write that last-minute proposal for you but you better believe it's going to be chock-full of dispensable lexical arcana.
