Playing the devil's advocate here. Suppose I use model A to do all heavy lifting (e.g. generating a bunch of good ideas) and then I go to the model B to complete the formalization. Accoring to a weird (unfair) tradition in math, the honors are attributed to the "last guy", which in this case is model B. That might have been a scenario OpenAI tried to avert. (Just a speculation)
