Correct.  PrimaryGroupID acts like a member link, but without being a
member attribute.  Users with primaryGroupID are members of the domain
group with that RID.

This is due to a bug/mis-feature of Active Directory Users and
Computers.  Unless you can show it is different on a Windows server, the
explanation is that the last objectClass value is used by ADUC to
determine what tab to show.  This in turn is determined by a sort of
objectClass values from least to most specific.
