J. Choe and M. Soret have constructed two families, which they call even and odd, of closed embedded minimal surfaces in the round $3$-sphere, all of which can be interpreted as desingularizations of certain unions of multiple Clifford tori intersecting with high symmetry along two great circles. They construct each odd surface by proving the existence of a minimal disc solving a Plateau problem in a certain prism. Here we show these closed embedded minimal surfaces are uniquely characterized by the boundary of their intersection with the prism, and moreover the intersection is graphical with respect to rotations along a suitable axis of the prism. This implies as a corollary that some of the high-genus desingularizations of Clifford tori constructed elsewhere by the authors are in fact congruent to odd surfaces of Choe and Soret of the same genus.
