An alternative fix is "if the HostPortPair was modified". Would you prefer that?

   bool RewriteHost(HostPortPair* host_port) const;
 
   // Adds a rule to this mapper. The format of the rule can be one of:
   //
   //   "MAP" <hostname_pattern> <replacement_host> [":" <replacement_port>]
   //   "EXCLUDE" <hostname_pattern>
   //
   // The <replacement_host> can be either a hostname, or an IP address literal.
   //
   // Returns true if the rule was successfully parsed and added.
