ICOT- You have forgotten a critical component- where is the gas coming from?
actually, the gas is piped in THROUGH the pilot light and runs to the burner. So, it is ignited by the pilot BEFORE it even reaches the burner (by sheer pressure) and the actual source of the fire is at the pilot light-not at the burner. When you reduce the gas intake the fire RETREATS from the burner and remains in the pilot light.
so-your conclusion is WRONG and one can easily assume that this is only one light that is made smaller.
