The standard views, eg. Front, Rightside, Right Isometric, etc. are described by specific rotations around the XYZ GroundPlane. When the User creates a Working Plane within the IJK space ( created by the 3 point selection method ), the XYZ GroundPlane rotational descriptors no longer apply.
Then the Working Plane palette is utilized to switch between the various coordinate viewing options. While in the Working Plane container, the GroundPlane is shown for reference, only... but ignored until the active Working Plane is switched back to the standard views for the GroundPlane.
