This isn't true for totems (unless my understanding is very wrong) and as far as I'm aware isn't true for any cams.
Totems do transfer the load from the lobes to the krab via wires, rather than the traditional axle and stem design, but these are different wires to the trigger wires. Totem have a decent little technical doc explaining how their cams work somewhere on their website.
To the OP: It's fine, but annoying if it snaps. Some of my cams have strimmer cord trigger wires now after the originals broke, quite a cheap way to repair and works well. Admittedly they're now spares so don't see much use, so can't comment on durability.
