While your analysis is correct (two potentially
unencrypted hops), the encryption concerns in
themselves should be irrelevant to the concerns of
tor.
Tor is not an encryption technology.  The only reason
for encrypting the other hops is for anonymity so that
each hop only knows about its immediate peers.  The
question is whether an unencrypted last leg affects
anonymity?  Plain text communication after tor should
already be considered compromised and if this leg were
unencrypted it should not be considered an additional
plain text compromise.
