That is all :)
Please do
man apt-get
to understand the difference between apt-get upgrade and apt-get
dist-upgrade.
Your above statement perhaps happened to be correct for the exact set of
updates available when you tested, but is not generally correct.

From the man pages for apt:-
upgrade is used to install the newest versions of all packages currently
installed on the system from the sources enumerated in
/etc/apt/sources.list. Packages currently installed with new versions
available are retrieved and upgraded; under no circumstances are
currently installed packages removed, or packages not already installed
retrieved and installed. New versions of currently installed packages
that cannot be upgraded without changing the install status of another
package will be left at their current version. An update must be
performed first so that apt-get knows that new versions of packages are
available.
dist-upgrade in addition to performing the function of upgrade, also
intelligently handles changing dependencies with new versions of
packages; apt-get has a "smart" conflict resolution system, and it will
attempt to upgrade the most important packages at the expense of less
important ones if necessary. So, dist-upgrade command may remove some
packages. The /etc/apt/sources.list file contains a list of locations
from which to retrieve desired package files. See also
apt_preferences(5) for a mechanism for overriding the general settings
for individual packages.
