If you read the man page, I think you will find that it is your
assumption about what the '-G' switch does which is incorrect.
Quote:
"-G grouplist"
"Set additional group memberships for an account.  grouplist
is a comma, space or tab-separated list of group names or
group numbers.  The user's name is added to the group lists
in /etc/group, and removed from any groups not specified in
grouplist."

Please note the part which says "and removed from any groups not
specified in grouplist"
