Perhaps this is about controlling which group is used when saving

Most unixes support the setgid bit on the directory which
forces all new files created in the directory to the same group as
the directory.  This is very useful if you know about it.  There
is a limitation though files moved from elsewhere into the
directory keep their original group ownership.

The originator may not have known about this Unix trick
or maybe this doesn't do what he wants.
