Yes, including 'shortcircuiting' the same way (you can check by having some ai define a __cmp__ which prints out some line of trace info). The single-cmp case is more general (since it also works for tuples of unequal length -- a shorter tuple being smaller, all other things being equal) and I suspect often speedier (but one would have to timeit for a few cases to check), but semantically they're the same.
