Does anyone know the answer to the "turn signal problem" he poses? Why does the beat frequency he observes match what he calculated?

Assuming you meant "doesn't", it's explained in the next section, the Zero-Delay Problem.

edit: The frequency equation solved for time, using the adjusted values from the table: https://www.google.com/search?q=1%2F%281%2F1-1%2F1.04%29
