The user can set it this way in purpose (since they own the directory).
It allows them to force the group that new files are created under (only
groups they are members of though, so it's safe). The user gains no extra
priviledges by doing this, so you can safely let them set it this way.
Other instances where this is useful is is group working directory, such
as a CVS repository.
