Yes, both photos which show spoilers and ailerons are pretty clear: Ailerons and rudder point in the correct direction, spoilers wrong.
But it also means that either the pilots at that point were applying reversed aileron input at that point on purpose, or in this case it was the *spoilers* (all of them) which were hooked up the wrong way (as opposed to the *ailerons* which were messed up in the Embraer case, at least according to the picture that was making the rounds). Which seems even harder to do than the aileron swap. But maybe someone familiar with the setup in the Bombardier knows how the connectors work...
