First, there's a terminal on which runs a getty, then login(1) is called for the authentication,  login's only available information is /etc/passwd.  After authentication, login sets $HOME to the correct value and starts a shell.  The shell relies on the fact, that $HOME has been set correctly by the logon procedure.

Hmmm... My /etc/profile.orig (I believe that's where I put the original 
/etc/profile before I modified it) has

# Set up USER's home directory
if [ -z "$HOME" ]; then
  HOME="/home/$USER"
fi

Seems to me it not only can, but does set HOME if it has not been set 
before. If that be the case then why should it guess at using 
"/home/$USER" instead of the home field in /etc/passwd?

I guess I just think that the value of %HOME% should always equal the 
value of home in /etc/passwd thus giving the user one consistent home 
directory.

Granted you're correct that if %HOME% was set and is not the same as 
/etc/passwd's home then perhaps profile should not change the value. 
However to me this seems like a receipe for disaster or at least for 
mass confusion...

YMMV
