QNE is not an altimeter sub-scale setting of 1013 nor any other setting. QNE is the altitude (amsl) of the airfield when the altimeter is set to 1013, or in other words the Flight Level of the airfield. It is only used in very high or low atmospheric pressures that cannot be set on the altimeter sub-scale, and is even less used with modern altimeters that can take very low or high pressure settings.
