It's correct but not particularly elegant as it duplicates
what passwd is supposed to be for.
I assume HOME is defined as a system variable in the Windows 
environment and it is the same for everybody. 
Is there a good reason for that?
Otherwise undefine it and everything will be well.

For reference, here is how HOME is set, in order of priority
- When starting from Windows
1) From existing HOME in Windows environment, translated to Posix
2) If the user has an entry in passwd:
   a) from passwd, if the home directory field in non empty
   b) from HOMEDRIVE/HOMEPATH
3) /
- telnetd and rlogind
1) From passwd, if it is a valid directory
2) /
- sshd
1) From passwd, even if it is invalid.
   In that case /etc/profile may actually create it.

Note that in all those cases HOME is never set in /etc/profile !
