Thank you Darren!
It could be PAM. What is odd is that the transcript you originally
posted does not contain the text "You must change your password now
and login again!" which sshd prints when it changes passwd by exec'ing
/bin/passwd.
Actually, once password has been successfully changed the login process
continues and you finally get a prompt. No need to go through the
"logout + login" procedure.
If you are investigating PAM's behaviour you might want to try the
test harness tool I wrote for this purpose:

Thank you! :)

Sure! :)
Where can I find instructions on how to setup my own build and
test environment for OpenSSH development on Ubuntu 14.04?
The general requirements and build instructions are in the INSTALL
file. The -dev packages you need for Debian based distros like Ubuntu
are listed in README.platform.
Any official OpenSSH design rules I should consider (apart from
following the style already used in the source code)?
OpenSSH follows the OpenBSD style:
http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man9/style.9
The initial dialog example (that motivated me to send the initial
email to the list) comes from a system based on SLED 11 SP3.
When checking, the actual dialog presented at login is identical
to what happens when you run the passwd command in the shell to
change your password. Thus it seems like the dialog texts does not
originate from OpenSSH itself. So the "culprit" might actually be
PAM...

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
