My take on this is the turrets manipulate the erector tube that carries the reticle and a couple of lenses, the erector tube is not angled but manipulated in the vertical and horizontal plane by the turrets.
When you optically centre you place this erector tube and its associated lenses in the centre of all the other scope lenses.

Willing to be proved wrong tho
The erector tube is pivoted from a fixed point at one end. Only one end is pivoted up and down. It's easier to explain with a diagram but I don't have the time to find one or draw one.

But yes, it's angled from one end. I'm sure if you google a bit you'll find an exploded view of the internals of a scope.
