That's a misconfiguration.  From "man 5 group":

   The group field is the group name used for granting file access to  
users
   who are members of the group.  The gid field is the number associated
   with the group name.  They should both be unique across the system  
(and
                              ^^^^^^^^^^^^^^^^^^^^^
   often across a group of systems) since they control file access.
