Previously it would bake viewed from above the surface. The new option can be useful when the baked result is meant to be viewed from a fixed viewpoint or with limited camera motion. Some effort is made to give a continuous reflection on parts of the surface invisible to the camera, but this is necessarily only a rough approximation.
