Yes, apologies, what I meant by "favored" was that in every department, women applicants were more likely to get an admission than men. But I'm pretty sure the admission rate can still be lower for women overall than men overall, using exactly the same scenario you described. If the sociology department admits 10 percent of applicants and the physics department admits 90, it seems very easy for gender bias in applications to shift women towards 10 and men towards 90, even if the rate is a few percent higher for women.
