  No.
  clipped_by works exactly like the intersection CSG except that it doesn't
render the surface of the second (ie. the clipping) object.
  bounded_by has little, if nothing, to do with CSG. You may think about it
as if it worked like an intersection CSG (but better not since you may get
surprises in some cases).
