No, it should not !

Have a look into the documentation. User Clip Planes have to be located
either in world space (for Fixed Pipeline) or in projection space (for
programmable pipeline).

What kind of effect do you want to implement where this behaviour causes
trouble ?

am able to get what I want to happen by using D3DXPlaneTransform(...) and
resetting the SetClipPlane(...) each frame with no real noticable frame rate

graphics API should do for you (I am relatively new to DirectX having used
OpenGL for a long time and I somehow remember OpenGL supporting this)
