I remember that video and couldn't find it, thank you. The sequence isn't just the 5 step 3-note motif shifting back and forth, it's the 5 steps, 5 again, 3, 5, 3. So 21 steps that are hard to hear it through the reverb. What makes it so good is the listeners ability to lose where we are in it so it never seems repetitive. Bach's work is simple on deconstruction too. :)
