I guess you are correct and that string is used by software-properties- gtk but also from the update-manager command during the upgrade process.
To reproduce install Ubuntu 16.04 in french add some other sources in /etc/apt/sources.list.d and then try to upgrade to 16.10 you will see an alert with an error.
