I'm having a problem using subplot to show the difference between lighting on two separate graphs

I'm trying to demonstrate the difference between phong and flat lighting on a sphere but when I try to plot them together using subplot both of my graphs are in flat lighting. If you plot the two spheres individually there is nothing wrong with the lighting but when plotted together they are both flat. What is the correct way to plot both of these with the correct lighting?

[xx,yy,zz]=sphere(30);

subplot(1,2,1)
surf(xx,yy,zz);
h = findobj('Type', 'surface');
set(h, 'FaceLighting','phong', 'FaceColor', 'interp')
light('Position', [1 3 2]);
light('Position', [-3 -1 3]);
material shiny;
axis equal;
title('phong');

subplot(1,2,2)
surf(xx,yy,zz);
h = findobj('Type', 'surface');
set(h, 'FaceLighting','flat', 'FaceColor', 'interp')
light('Position', [1 3 2]);
light('Position', [-3 -1 3]);
material shiny;
axis equal;
title('flat');

findobj() by default searches for all descendants of the root object, so the second call to findobj() is going to find both surfaces.

Adjustment: change

surf(xx,yy,zz);
h = findobj('Type', 'surface');

to

h = surf(xx,yy,zz);

Thanks a lot!
