So if you run it on a server and the group isn't local to the server this wouldn't work:
<code>_group [[deleteGroupWhenEmpty]] [[true]];</code>
But this would work:
<code>[[if]] ([[local]] _group) [[then]] {
    _group [[deleteGroupWhenEmpty]] [[true]];
} [[else]] {
    [_group, [[true]]] [[remoteExec]] ["[[deleteGroupWhenEmpty]]", [[groupOwner]] _group];
};</code>

The auto-deletion of a group is not automatic. For example, if you place a group in editor, name it (grp1), and kill the units in preview, this group remains not null and is counted as group (checked by count allGroups). On the other hand, if you write: this deleteGroupWhenEmpty true in composition init (group init), this group will become null sometimes after the units are killed. It takes a little time for dead units to exit the group, then an extra time for the group to be deleted once all units dead. (count allGroups decreases). Of course, in both cases, grp1 remains a variable ("grp1" is not nil).
