Surprisingly, they are using the term correctly. Although it seems that the main point of the post was to plug their "Colossal AI" framework but if you do an in-page search for "Low-cost replication of ChatGPT" subheading midway in the article they do claim to replicate RLHF thingy fully whatever it might be. Interestingly, they also suggest that it would work with both BLOOM and OPT meaning that you can potentially make things like ChatBLOOM and ChatOPT (even on a consumer grade GPU). Lack of demo doesn't inspire too much confidence though.
