Yeah the "previously" segment has changed quite a bit since China, I think. Instead of simply recapping the previous episode, each segment usually recaps the whole season now, or at least the more over-arching themes. For example, every week in Gabon we would hear about how Kota was decimating Fang, and they'd show clips from the first episode challenges. And in Micronesia we were reminded every week that Jason had found a fake idol until Eliza played it.
