It ensures that the root shell has user root's environment, and thus 
doesn't pick up any silly wack-assed stuff from the non-root user, such
as unsafe additions to $PATH.  

If you're saying that "sudo -i" also does that, fine.  That was not
entirely clear from the manpage snippet I quoted -- whereas it's very
clear that "sudo su -" does it.
