Hello Matthew Paul Thomas. Thanks for your answer.
If I turn off automatic installation of security updates, I will be notified immediatly of security updates, and other updates will be notified at the same time (default behaviour of update manager). I don't know if it's possible to turn off notification of security updates, do you know ?
But this logic bug seems to have been already identified in this bug report in 2009 ;)
"This maybe a usability bug. update-notiifer just checks when the last apt/dpkg action was performed
and calcualtes the 7 days based on that. But from a user perspective installing a new software and
installing a update is something different so it may not be clear why update-manager does not appear
in this situation."
"Since Add/Remove is currently incapable of installing updates, and therefore using Add/Remove doesn't mean you've decided to defer updates, it would be nice to exclude use of Add/Remove from resetting the 7-day timer."
