Quite simple.  When you run "ssh" it calls "sshd" through a socket
connection.
sshd is running as SYSTEM.  It is unlikely that the home directory for the
$HOME
directory for SYSTEM is the same as your home directory.   Since "sshd" is a
unix
program, not a Windows program it uses the standard method of setting the
$HOME
environmental variable, which is to look it up from /etc/passwd.

For example, on the computer I'm on now, my $HOME is /home/docbill .  My
wife's $HOME is /home/olivia .  SYSTEM's $HOME is /home/SYSTEM.  So if I do:
        ssh -l olivia localhost
sshd has to find out what my wife's home directory.  Not my home directory,
nor SYSTEM's home directory.  If instead it where just to use the current
value of "$HOME", I could change it to enter my wife's account even if I did
not know her password or the Administrator's password.
