Either I've misunderstood you, or this is completely inaccurate.
What do you mean exactly?
Someone able to watch and modify traffic can wait for authentication to occur
and then take over the connection. So you don't know you are still
communicating with the party that did the authentication. You need something
protecting message integrity which is normally based on encryption, but I
think there might be ways to do that with just hashing.
