I guess the idea of it is, once some contact opens the C-circuit, it won't pick back up right away, but instead C will just drop out and stay out, (tell-tale CX then coming in), until the safety circuit has been cycled, and then C will pick back up, as has been said. Maybe to keep cars from starting, and stopping repeatedly, in case some issue exists, like maybe a broken tape switch bouncing open and closed. So they wanted to get the car to stop, and stay stopped, (C/CX lockup) until it has been checked out. Just guessing.
