That's because the password prompt comes from pam_unix.so which is
'required' and called first in your configuration, and AFTER that the
bioapi module is called which tries to authenticate and even succeeds,
but since pam_unix.so is 'required' it doesn't matter any longer.

Change the ordering to call the bioapi first which is 'sufficient' for
the authentication to succeed, but if it fails it will fall back to the
'required' pam_unix.so module.

BTW, that and a lot more is explained in the PAM documentation at
http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/pam.html .
Somebody just needs to read it. ;)
