Redundant Minimap Settings

I will have to go back and look at past titles, but I don't recall two settings doing virtually the same thing.

How will these two settings work with each other?

Advanced HUD Settings (MINIMAP):

View Rotation: Enable minimap to follow the direction the player is facing. 

Dynamic Minimap: Enable minimap rotation with player view.

Unless I am having an aneurysm, these sound like they do the same thing and unlock the minimap so it rotates and is not locked to North.
