You want the operations of a private type to have visibility on the
components of all visible objects of the type.  E.g. P(X,Y) should
be able to see the implementation details of X and Y (assuming P is
in the package where the type is declared).

You want the operations of a protected type to have visibility
on the components of just that object (the one that was locked
when entering the operation) -- not other objects that happen
to be of the same type.
