I haven't been able to find this explained anywhere.
My
guess is that it's some kind of lockout where the engine will refuse to start if it's on the ground and believes it's unsafe to do so, potentially implying a maintenance reset. If you tried to start an engine with a genuinely stuck open fuel valve, you might get a fireball or a sudden acceleration up to maximum thrust, knocking the aircraft off any chocks or parking brakes.
