su does not load .bash_profile and therefore is a completely different application than with any other user. This one is different, considering .bash_profile is indeed used for logins for other users.
su is an application for switching from one user to another. It behaves the same way whether you are switching from user A to user B, or to user root.
su is NOT the same as logging in with that user ID. If you login as root at the console, root's .bash_profile would be read.
