Why do you think that this set is open?

Just take a point of the interior of such that (if such a point does not exist then is constant), then there is a neighborhood of such that is bijective on . That means and are continuous (because analytic). And the preimage of an open set is open under a continuous map. So the preimage of under is open and so we find arbitrary many points in such that .

Oh no its both the same here.
