Correct me if I'm wrong, but packet headers must contain a public destination address so that they are relayed to the destination server.
That means any host they pass can pickup that they are heading for DDG. There goes your IP for TCP connections.

Use the DDG Onion exit node perhaps? (If you are this concerned).
