Your shell cached "python" to mean "/usr/bin/python". It is not
evaluating the full PATH on every command invocation as it would be
quite slow to walk the filesystem every time.

This cache will not be updated unless you tell your shell to do so.
Either run 'hash -r' or close and reopen your terminal window.
