These commands do not centre the objects in the perspective view (in this example a named perspective view). I can’t remember this ever being a problem in Rhino 5 but I see there is a similar post in Rhino for Windows

A sidish view of the camera also shows what’s going on. The effect is more pronounced the longer, in the view direction, the objects are,
