 > The reason the member may be either a reference or a copy is simple. The
 class is a view, which means most of the time it will contain a reference
 to the actual type is adapting. However, a view could also be adapting
 another view, and in those cases it should contain a copy to the view
 rather than forcing the user to define additional named variables for the
 intermediate views. Then one can chain views the obvious way.

 Why it needs to copy the view? A concrete example will help.
