That's the bit I've never really understood.
I've always reasoned that if the system behaves as if a bulb is out, that would tally with an ultra high or infinite resistance, not the ultra low resistance of an LED.
In other words, it would behave as if the bulb had been short circuited (low resistance path) rather than blown (infinite resistance path).
