 It is unlikely that the client port number is the same on two different
 connections; validating the port is therefore unlikely to be successful.
 
-If the client has a token received in a NEW_TOKEN frame on a previous connection
-to what it believes to be the same server, it SHOULD include that value in the
-Token field of its Initial packet.  Including a token might allow the server to
-validate the client address without an additional round trip.
+A token received in a NEW_TOKEN frame is applicable against the servers that the
+connection is considered authoritative for (e.g., server names included in the
+certificate).  A client MUST only use a token that is applicable to the server
+that the client is connecting to to.  If the client has a token received in a
+NEW_TOKEN frame that is applicable to a new connection attempt, it SHOULD

Thank you for the suggestion. I believe the intent here is to recommend the use of tokens when appropriate; hence went with e67d713.
