Like you, I was assuming that the position of the cylinders would be the input, but I was thinking of using just the airflow directly as an output rather than the position of another switch.

I was just trying to satisfy Paul Kreig's desire to have a reversible engine, and it struck me that a differential was an easy mechanical way to do it. I love differentials. (...)
