This rule mandates re-dispatch.

There is no substitutability issue when manifested types of objects are
honored. Actually it is the "simple dispatch" rule which can potentially
violate substitutability by using the type T in place of the type S when
dispatching to the operation of S.
When the object is declared of the type T it is no matter whether it was S
in one of its earlier lives or not.
