A modern ABS most probably WOULD have kicked in and WOULD have catched her.
However, as you state she has a more pavement oriented tire than you, there is a chance she would have been too fast for the turn even without braking. And oh, in my experience it takes huge balls to rely on the ABS under these circumstances.
