AFAICT, the translators themselves are just rewriting addresses and not paying attention to 'connections', which is all to the good.  But then we get to this:

5.2.  Recommendations for Application Writers

   Several mechanisms (e.g., STUN [RFC5389], Traversal Using Relays
   around NAT (TURN) [RFC5766], and Interactive Connectivity
   Establishment (ICE) [RFC5245]) have been used with traditional IPv4
   NAT to circumvent some of the limitations of such devices.  Similar
   mechanisms could also be applied to circumvent some of the issues
   with an NPTv6 Translator.  However, all of these require the
   assistance of an external server or a function co-located with the
   translator that can tell an "internal" host what its "external"
   addresses are.
