from login.1

The  login  program is NOT responsible for removing users from the utmp
       file.  It is the responsibility of getty(8) and  init(8)  to  clean  up
       apparent  ownership  of  a terminal session.  If you use login from the
       shell prompt without exec, the user you use will continue to appear  to
       be logged in even after you log out of the "subsession".
