Why do you expect it should change as long as the inner loop is running?
As you can see from the increasing pixel_y_metres the inner for loop is
still running. This is the same as:

for a = 1:3
  for b= 10:12
    printf ("a = %i, b = %i\n", a, b);
  endfor
endfor

a = 1, b = 10 #your screenshot
a = 1, b = 11 #your screenshot
a = 1, b = 12 #your screenshot
a = 2, b = 10
a = 2, b = 11
a = 2, b = 12
a = 3, b = 10
a = 3, b = 11
a = 3, b = 12
