I don't think the author talks about intuitive thinking in positive vein. Whatever is not analytical is named intuitive. However, the real definition of intuitive is probably that kind of thinking that comes out of subconsciously learned patterns and not from proactive conscious thought - often cited in the usual example of Friedrich August Kekulé discovering the benzene structure from a dream of a snake biting its own tale.
