The pedagogical structure he is using is known as "programmed instruction." It was popular in the 60's through the 80's for many kinds of technical instruction. One of the interesting characteristics about it is that its progression always seems very easy (often too easy) because it takes small steps and uses repetition. This ensures that the learner is ready for the subsequent step. It is highly effective if you want the learner to understand a specific set of details quickly. I like it in this context.
