Why do drawing commands, such as rectangle and line, ignore hold?

I am trying to display a changing rectangle in a loop with a pause, and it ignores the commit (which is actually assumed to be the default).

Here's a simplified version code:

clc; close all; clear all;

rect = [10 10 20 30];

figure
axis([0 200 0 50]);

for i = 1 : 15
    rect(1) = rect(1) + i;
    rectangle('Position', rect, 'edgeColor', [1 0 0]);
    hold off;
    pause(0.2);
end

Is it on purpose? Am I missing something? What can I do to make the previous rectangles disappear, except that they are printed in white after each iteration?

Thank..

edit:

A very simplified version has been resolved, but if I also want to draw one more thing in the same figure, the other section is ignored. What should I do in this case?

Thanks again.

clc; close all; clear all;

rect = [10 10 20 30];

figure
axis([0 200 0 50]);

h1 = [];
for i = 1 : 15
    rect(1) = rect(1) + i;
    delete(h1);
    h1 = rectangle('Position', rect, 'edgeColor', [1 0 0]);
    hold on
    plot (5 + 5 * i, 5, '*g');
    hold off
    pause(0.2);
end
