I see. Thanks for the clarification. Yet, it is still better to use distinct topic role constraints, because otherwise i cannot prohibit 'continent' from being a 'containee'. Because in the above model both topic role constraints (for container and containee) work on the same (abstract) super type A.

Correct?
