I see you managed to find it all by yourself. Well done!
What page in that 32 page document does Google tell us to do this crap?
Google specifically says ...
URLs with words that are relevant to your site's content and structure are friendlier for visitors navigating your site. Visitors remember them better and might be more willing to link to them.
Google also advises against the use of excessive keywords as in Shatner's original example
avoid using excessive keywords like"baseball-cards-baseball-cards-baseballcards.htm"
Google uses this example ...
and states ...
www.brandonsbaseballcards.com/articles/ten-rarest-baseball-cards.htm A user performs the query [rarest baseball cards]. One of our deeper pages, its unique description meta tag used as the snippet, appears as a result.
Shatner's example has ten hyphens after the final slash. Google's example has three with no repeated words. Base your conclusions on this.
