You've got QNE slightly wrong. It's not 1013.2 (That is termed the Standard Altimeter Setting) BUT (and this is the concept people find hard to grasp) it's the LEVEL indicated when 1013.2 is set. Used mainly in high or mountainous environments where you want an indication of height as a landing datum (much the same as QNH) but with the advantage that when the pressure is low (most altimeters can't go below 950mb) it gives a reference that is available to use.
