I think that is only partly correct. With "sudo su" I have $HOME set to 
"/root" while it is still "/home/$USER" for "sudo -s". That is an 
important difference if I then start an application that modifies 
configuration files and changes their permissions in $HOME. It may 
therefore prevent further access to those files by the original user and 
the application run as normal user may no longer work.
