Horn's statement about having a mania for recording coversations struck me as a key insight into Wolfe's writing. Could it be that Wolfe's eliptical style is largely based on a preference for writing conversations rather than describing actions? I'd have to do some more reading with this idea in mind, but I have the impression that quite a lot of the gaps in Wolfe's narratives come when a conversation is interrupted by some event, and we skip the event for another conversation in which someone may or may not describe or allude to the event itself.
