I could easily imagine a scenario where you do know something about a guest - enough to see that they are a compelling speaker, or have an interesting area of expertise that an audience would appreciate - without being fully "read in" on that person.

It's like when you go to a lecture hosted by an institution and they give a little intro about the lecturer beforehand. Most likely some of those little facts about the person's biography weren't known to the institution when they invited the person - they did a little extra research later to prepare the intro. They may not have known what state the person grew up in or where they did their undergrad but they looked it up in case it helps someone make a connection.

So it's just LLM deep research as I mentioned, something that's a feature that many LLMs have these days.
