It seems to be contradictory, but it is not.  You often cannot control
the certificate of your peer server.  In case its certificate is issued
by a large CA, you really want to make sure you're connecting to this
specific server, and not any other server with certificate issued by the
same CA.  Web browsers use CNAME/SubjectAltName verification to solve
the same problem in a different way.
