No, this is rendering properly - as the documentation states (section 2.3.1.1.5)
look_at may change up and/or right.  (In this case, it rotates right by 180
degrees to keep the effective system left-handed.)  If you were to move the
right _after_ look_at, you'd get the result you're expecting (and incidentally
you'd be turning the coordinate system to be right-handed as a side effect).
