I'd expect either [1,2] or [2,1] depending on whether it's py2 (where dict
iteration order isn't guaranteed, so could be either) or py3 (where dict order
is more stable/guaranteed)

While I have difficulty imagining a case in which I'd find this useful, if I
were writing this code, it's the "useful" result I'd expect.

I'd file it in the "whatever" category, possibly useful to someone other than
me.
