That isn't necessarily true.  Upgrade allows the connection to be switched
to some other connection-oriented protocol.  There is nothing to stop that
other protocol from defining a similar mechanism for switching back.
However, that is the purview of the other ptotocol, and thus wasn't
defined as part of HTTP/1.1.
