Yes, this was especially interesting when he talks about rewatching 'The Sound of Drums', and how he can see why people sometimes think he's just making it up as he goes along, whereas instead he's deliberately skipping dull bits. It was very reminiscent of some of what Grant Morrison said about Final Crisis which, again, I don't think was entirely successful, but was certainly a valid experiment.
(Interesting also to see about how much he rewrote on stories by other writers which we assumed were better just because they weren't him, like 'Family of Blood')
