Yes, it stacks, but not quite like that. She would lower enemy's DEF by 40% once, and then she would lower enemy's DEF once again, except the enemy's DEF would actually be different this time, since it would have already been lowered. So the actual result wouldn't be -80%, but -64%.

However most enemies still have damage reduction percentages, so it wouldn't really be noticeable either way.
