It's hypnotic (their patter) in some strange way...
Al Goron makes such a stupifying statement (as is his/their way) that 'their' brains must, upon first reception, naturally attempt to discount, (what is) the notion that they've just heard, (as being unbelieveable), yet onward/undaunted they continue, struggling with the mental process, in order to reconcile the syntax as factual because he (their leader) says it's so. Whew! It's tough being a liberal!
amazing, ain't it bump ;)
