It doesn't apply. It refers to memorable brainwallets extracted from existing texts using schemes. No single condition of those three applies in here.
Well what is this below if not a scheme?
If I type a long paragraph talking about a random topic on my mind, I can tell you with all practical certainty that no other human being will come up with the exact same string, regardless of whatever method he uses to generate strings.
There was a guy who created a brainwallet from some text in Afrikaans language. He thought he was safe because it wasn't in English. Somebody guessed that text and he lost all his bitcoins.
Human beings aren't very good at this sort of thing.
If you insist on doing this at least use a pbkdf like scrypt instead of a fast hashing function. Google warpwallet for one example. Again gmaxwell is going to complain that no javascript implementation is going to be good enough because its too slow compared to what the crackers are using.
