Does S=co(Ct(S)) hold in hypergraphs (S: convex subset of vertices, co: convex hull, Ct(S): contour set of S)?

In Theorem 5 of [1] it is proved that for any graph G if S a convex subset of vertices of G, then the convex hull of the contour set of S equals the original set S: S = co(Ct(S)). As noted by the...
