In english the word "scooping" implies that but perhaps not as definitavely as
you have stated it.

You might be right here.
Intersections will slice or cut an object and then apply a face where the
slice has been made.
Clipping slices an object but will not leave a face where the slice has
occured. Instead the object that has been sliced will now appear to be
hollowed out since all solid objects in POV-Ray are not truly solid.
