I agree with the general message but his method is essentially what he is arguing against, an aesthetic. Note taking systems are bad because most of the time it is square peg and round hole. Develop the structure of your notes around what you are taking notes on or what you are taking notes for.

Take notes to publish; any other endeavor is futile. Pure learning sounds okay, but without the grinding wheel of application--hypothesis, experiment, failure--there's no reinforcement of concepts.
