I just thought that when she was attempting to take over Seilah, only part of her was taken over; which was her curse. And because it's usually when she can only fully ultilise a demon(can't use satan soul magic when she hasnt used Take Over) when she completely taken over it.

And because she couldn't fully Seilah, it makes Macro to be unstable and unable to sustain using it anytime she wants, if you know what i Mean.
