Well I don't know what you are referring to, but I'm not going to argue about your perception. I listened to the whole thing again (there are usually things that pass me by the first time, so I don't mind doing that for the interesting episodes) and I don't know how he could have done a better job at steering the conversation. He's a podcast host; he needs to pick at the parts that are of particular interest to him and his audience in a limited amount of time, as well as keeping the level of technicality just right so as to be digestible.

For someone familiar with the topic, it's natural to feel like they could have gone on about something at a more advanced level, and for someone entirely unfamiliar, it's natural that they would want to linger on things they don't quite get instead of moving on to something else.

Anyway, I'm not really going anywhere with this. Just curious about your perception since I tend to think of SC as someone quite smooth and approachable around people (unlike me). I guess even he can't be smooth enough for everybody all the time.
