Why would you set a new instance of a class object to an already existing one?

Why would you set bigPhone equal to phone instead of creating a new instance? It's obviously a different phone so why would you set it to a different instance of the same class? I'm having trouble understanding the use-case and why you would have to worry about overriding the original phone.

Sometimes you don't have access to the original class. Sometimes you can only interface with the class through a reference to the class.
