This is something that is also detected, but will automatically switch between main and reserve paths... assuming the other one is good. These sort of switches do so instantaneously and often are barely noticable on air.
So in the case of the Britain’s Got Talent fault of 2018 where the severe thunderstorm over London caused it to be off air for over 10 minutes, I’m guessing it took out the main and reserve so what we saw was this…
