You're on the right track, but this isn't correct. The turrets are reacting against spring pressure. The most relaxed position for the springs are with the elevation and windage turned all the way out. The most compressed position for the springs is with the turrets turned all the way in.

The reason you want the scope adjustments centered is because of the geometry or how the turrets contact the inverter tube. Turrets will only contact the inverter tube at a 90-degree angle when the inverter tube is centered inside the scope tube.

Here's a picture kinda showing what I am talking about.
