It's setting $PATH, as it's expected to do; it's only supposed to be run
once in a "session" (~/.bashrc being the other one).  rvm is a shell
function that modifies your PATH and assumes, as most things do, that
~/.bash_profile is not re-run within a session.  rvm's own setup in
~/.bash_profile is probably confused by it being re-run again; this is not
unusual, because you're not supposed to re-run it.

The only other thing I can think of is maybe it's expecting a symlink
somewhere which is being modified by ~/.bashrc (which is the shell config
that is read on all shells) and sudo is triggering it to be run (but as
root, not as you, so if it's doing this it should be causing more visible
issues.  Although it may know enough to make sure any link is owned by you,
specifically because of sudo).  This could happen with anything that runs a
subshell, sudo being probably the most common case for many people.

If you pastebin your .bash_profile and .bashrc somewhere I can probably
help decipher what exactly is going on.
