I can indeed. The original motivation for this property is a system
where at some point I created a group (I think with groupadd) with gid
1001. Later, after creating several users, I noticed all of the gid's
were one off from the uids.

Here I am only setting the gid of that identically named group (username
occurs twice, once for the groupmod, once of the usermod). So I think
this case cannot arise.
