Doeas the AppNotifications plugin uninstall any previous versions?

I love this plugin AppNotifications:

https://appstore.sdl.com/language/app/appnotifications/1020/

because it notifies, downloads and installs updated plugins all in an automated way.

I'd like to confirm that the plugin takes care of uninstalling any previous versions, I mean that a manual uninstall via Plugin Manager is not needed any more.

Am I right?
