How can we be sure that x_1 is not equal to x_2? It is possible that x_1 is less than 1/2 units away from p and is the only point that is in the two balls, then certainly the intersection is non-empty but we don’t get two distinct points.

Should we not remove that possibility completely by considering the new ball as entered p with radius d(x_1, p) / 2? That way we know the next point x_2 cannot be x_1?
