You are right. I think it's because like you pointed out, he "literally just sits there and lets the guest talk for 20 mins at a time"... this is what actual journalism is. It is not scripted and leading questions. If the interviewer talks more than the person being interviewed it's a pretty good sign that someone else is driving that car. I also picked up on watching the Bob Lazar episode that Rogan made reference to their dinner the night before; I'm not sure if he spends time with most guests like this, but it would certainly aid to the more personable and casual feel to his show - again, more like a conversation than interview.
