The string in your scenario bridges the lagoon and crosses the island.
Well, my curved "atoll" frame effectively has no vertexes (or ALL vertexes), so it is NOT a polygon. Perhaps, a topologically proper string "wrap" should enter and follow around the shore the lagoon? I guess not.
It appears that the rules clearly are meant to discourage curves in general, and all but the shallowest of concave perimeter shapes in particular.
