Yes, that's exactly what it means. This is a design decision which
allows you to roll back to an older version if there are problems with
the new one.

You can uninstall older versions with `sudo port uninstall name
@version` (just copy & paste the name and version from the output of
`port installed`). Or you can uninstall all inactive versions at once
with `sudo port uninstall inactive`.

If you wish, you can use the -u option when upgrading to immediately
uninstall the old versions after installing the new ones.
