The way I see it, the author oversimplified the password examples to make a point. When it comes to the password length he first made the assumption that your password wasn't in the dictionary. Then he gives us two password examples, the first one is predictable but long, the other one is unpredictable but short, and then he goes on to tell us that the first one is safer which, assuming you are up against a brute force attack, is true.

But the examples are oversimplified and might lead to worse password if a certain group of people come across the post.

P.S. My favourite tip for passwords is not to only have a password that is as random as you can memorize and never, ever, no matter what happens, write it down anywhere.
