Well, on AT&T Sys V, the group file is used just to define the alpha string associated with the group number and for the "newgrp" command to allow a person not logged into the group to change to that group. So, if you do not log into the group and need to get into the group (and realy DO want to use "newgrp"), you must have your login id there to accept it. If you log into the group, though, you are already allowed by the passwd file entry, so the group file line does not need to have your loginid in it, unless you newgrp away and want to newgrp back.
