From a system design, i would question any engineer that feels the need to have two cutout (a primary and a back up) when the whole systems is based on a single input and a single actuator. The CB is already a back up of a failing cutout switch. The understanding of the reasons why such idiotic cut out system was designed is the basis to fully understand how the whole system was though... or NOT
I guess
1. because they tried to make the cockpit appear as similar to the previous versions as possible and
2. two switches in series are a big factor less likely to fail closed than one
Two birds with one stone...
