Check the man page for rm:
-f Attempt to remove the files without prompting for confirma-
tion, regardless of the file's permissions. If the file does
not exist, do not display a diagnostic message or modify the
exit status to reflect an error.
That's what's happening the second time through. The first time, your
current directory is getting removed (so ../ won't refer to a real
directory the second time around). The bug is really in rm(1)'s initial
diagnostic message.

We thought time travel was impossible. But that was now and this is then.
