In other words, while it's useful from a password complexity standpoint to utilize longer passwords, and while this makes remembering them easier, it doesn't change the fundamental issue that managing many unique passwords is difficult for most people.
This leads to the same general mistakes (that password manager application users don't face):
1. Reusing a password (in this case a better one, but the problem remains)
2. Writing all of their passphrases down somewhere.
In general, I still prefer the use of pass phrases versus passwords, but this still requires a password manager for most people to be able to affect safe password habits.
(Thinking of this grammatically it's also interesting that we still refer to a group of jumbled characters as a pass'word.')
