If you are worried about improper engine out response at low altitude, your apprehension is a sign you are not ready for the worst case of a new student pulling the wrong throttle, stomping the wrong rudder and rolling the plane. The latter can of course quickly devolve into an unrecoverable spin. Even docile trainer twins have been lost this way, I recall an AllATPs Seminole a few years ago rolling over to a loss. The thing to do is get a more advanced MEI to take a short ride with you, you on the right him on the left, and have him deliberately demonstrate improper student engine-out response recovery. If he knows the airplane well he should be able to let it go pretty far to let you see what can happen, how it happens, and what to do to prevent or stop it. When you have that experience, the rest is easy because nothing can be more dangerous.
