What does the command 'diff-reverse-direction' do? The docstring only
says it "reverses the direction of the diffs". Does that mean changing
diff -c /home/xfq/.emacs.d/backups/.emacs\~ /home/xfq/.emacs
to
diff -c /home/xfq/.emacs /home/xfq/.emacs.d/backups/.emacs\~
?

It's part of diff-mode.el, which does not run diff but only helps you
read/manipulate diff's output. So what diff-reverse-direction does is
to let you see the result of swapping the arguments (as you have shown
above), without having to re-run diff.
