I was just looking at the javadocs. It all seems pretty logical... this seems a lot better than contaminating the realData by inserting statistical data from the overall user community that might skew the results for smaller clusters.
To divine what could be an example in your book on the subject, it is nice to be able to recommend bands that are like both "New 2 Town" and "Bowling in Hades" to an anonymous user (because statistically, my community could be evenly divided in their fandom) and then to only show bands like "Bowling in Hades" once the user logs in (since users like "the logged in user" only like that particular band of the two).
