No, it's really two storages in the same terminal, and you can switch
between the two. Programs have gotten used to having to do this by
themselves when the terminal doesn't support it, but having it supported
improves support, efficiency, etc. and provides some support that you
can't have otherwise. For instance, start an editor such as emacs or vi,
and quit it. With the alternate screen support (which they make use of
then) you will get back to the content you had before starting the
editor. Also, if you run an external command from the editor (e.g. :sh
in vim), you will also get back to the content that you had before
starting the editor. That can be really convenient when you had run some
stuff on the shell, and edit some file only temporarily and get back to
your shell work.
