Canting the rifle takes some of that upward angle and converts it to an angle in the horizontal plane. The obvious effect is that the horizontal component will cause the bullet impact to move in the direction of the cant.
The less obvious effect is that because some of the upward angle that was supposed to fight the effect of gravity is now doing something else (moving the bullet impact to the side), the bullet will now impact lower on the target.

That's right. There is minor reduction in elevation, but so small that it can be neglected in practice except for a large cant of course.
