I think he does mean runtime binding, as with a virtual function call. But probably more extreme - instead of a lookup table to find the static type, a message is simply sent to the receiving object. The object itself then handles it based on its type definition (which itself could be defined at runtime).

And the object can handle messages for which no function exists at all.
