No idea honestly, but reading the NHTSA report[0] on the whole unintended acceleration debacle, they seem to corroborate what I said.
Relevant quote: “In the few cases where the brake and accelerator pedal were applied at the same time, the brake override logic performed as designed and cut motor torque.”

That kill switch as listed above works by releasing the current that holds a relay that keeps the mains power connected, break the loop and it will take a lot of doing to get it back up again. There is no 'logic' involved, no electronics and there are no semiconductor bits & pieces in a typical e-stop chain (at least: there wasn't when I was working on stuff like that), just a plain electromechanical device. The only way in which it could theoretically malfunction is if the contactors of the mains relay had fused.
