I haven't checked if it ends up with that in every case.  However, a
variable can be changed or dynamically bound so that it might not end up
like that.  Or note this in rect.el:

(add-function :around region-extract-function
  #'rectangle--extract-region)

That it makes no difference in the default case doesn't mean it makes no
sense in general.
