As several have answered, I would have said that sharing means that you have a parent and daughter(s), where the daughter was attached asking for sharing. Sharing can "propagate" to whatever nesting level of subtasks you have created.
If there are no longer any relevant daughter(s) then "by definition" there is no sharing. The owner of a subpool is not changed by sharing. All private task-owned storage is freed by the system when the owner terminates. Since the owner cannot terminate if it has any daughter tasks, sharing is not relevant to the question of freeing by the system.
