Vortex Razor HD 3-18x50 max elevation

[CamouMan]

on the Vortex website it claims this scope has 71 MOA of elevation adjustment but then says "Turret design allows expanded adjustment range when L-Tec zero stop feature is disengaged for zeroing purposes. This MOA scope offers 120 MOA total elevation adjustment and 69 MOA total windage adjustment"

Can someone please clarify the max elevation adjustment? Does this mean you need to loose your zero stop position to get max elevation?

Higher power but I think same rangeonly adjustment.
I was given this response in a email from a friend there.
On the 4.5-27, three turn turrets limit usable MOA travel range to 75 moa (approx. 37 up, 37 down on square barrel/receiver.
