Actual output from emerge:

# emerge -C sys-devel/gcc:{6.4.0,7.3.0}
 * This action can remove important packages! In order to be safer, use
 * `emerge -pv --depclean <atom>` to check for reverse dependencies before
 * removing packages.

The unmerge list is ordered, so that packages are not unmerged before their dependencies (which can matter for pkg_prerm and pkg_postrm phases). The split output in the display is a result of the ordered list (unmerge order is visible).
