Hang on a minute. Are they saying that freshness is an algo factor or that the algo is applied to pages even the most recent ones?
If Caffeine folds in new pages and churns the index more regularly and incorporates new pages applying the same algorithm to old and new alike then that has to be a good thing. What it means is that new pages that deserve to be ranked for a term get ranked almost immediately they don't have to wait for the monthly update to get incorporated.
If they mean that fresher is better and so give fresh pages an extra boost that's just doolally.
