In my Worldwide Satellite Launches I call the second object which the
four-stage Proton-K leaves in LEO (other than the Proton-K third stage) as
the "fourth stage casing". At launch the Blok DM class fourth stage is
encased in a cylinder and this is discarded in LEO after separation from
the third stage and before the fourth stage performs its first burn.
Since it is a hollow cylinder it always decays from orbit far more rapidly
than the third stage.
The payload fairing is completely different, since the fourth stage casing
does _not_ cover the payloads at launch.
