That may seem like a stupid question, however; I'd like to think of it more as an uninformed question, as I know that when using an ohm meter and checking for continuity between the front and rear pickup rollers, you get continuity at even the most sensitive setting which would seem to indicate there's no internal circuitry in play between the front and rear rollers.
The center rail rollers are connected together, they are the same electrically, as you have discovered.
A TVS diode stays in the circuit, takes a licking, & keeps on ticking. It will clamp overvoltage spikes continuously down to their rating, there is probably a way to demonstrate this with an oscilloscope. They do not require scheduled replacement.
