At one company we worked we had a courtyard and for some reason there was a separate office outside the main complex all on it's own - we suspect it was a repurposed visitors or security center.
We then noticed that people moving into it never came back to the main building but left - we started calling it the "departure" lounge :).
He is in the "departure" lounge - he just needs to figure it out that his time at OpenAI is over.
