man su says:

       For  backward  compatibility,  su  defaults to not change the current 
directory and to
       only set the environment variables HOME and SHELL (/plus USER and 
LOGNAME if the target
       user is not root/).  It is recommended to always use the --login option 
(instead of its
       shortcut -) to avoid side effects caused by mixing environments.

[emphasis added].

That might have something to do with it. What happens with ~ might also
matter. How does emacs find the init file?
