The idea is to move the 'control polygon' of curve X closer to point p as long as the previous delta > distance-to-point-on-cloest-curve-Y. When that is no longer the case, X is not going to be closer than Y. So in fact you don't need X's exact closest point, because you know the next subdivision will never move closer to ...
