That's incorrect. One of the differences between apt and apt-get is that apt WILL install new packages when doing "apt upgrade" (but it will not remove existing packages). Another difference is that apt will remove all of the .deb files from /var/cache/apt/archives that were downloaded for the CURRENT apt command session (but will not remove any that were already there). (This behavior can be changed in a config file.)
