The reason it feels inverted is because it's not "click and drag" in the normal sense (like Google Maps) where clicking and holding sets an anchor point, and moving the cursor moves the anchor point.
This is more like a virtual joystick. Clicking and holding establishes the neutral point of the joystick, and the cursor position relative to the neutral point is the velocity vector of camera movement. It behaves the same as the right hand joystick in a console FPS like Halo with a traditional (non-inverted) control scheme.
