Very unlikely, because I know the name :). They are huge corporations with very prominent links (like pepsi would have from financial sites, blogs etc) vs a much smaller non-profit site.
That doesn't prove an algo change. The rankings could have changed because Caffeine includes deeper crawling, and so additional data could have been factored into the calculations, thereby causing the other site to move up.
