If instead of only simply observing, they intervened, then from that point on any other attempts would also have been intervened. As a result the number observed would've been less than 12%.
Now consider a polling station that they weren't observing, then the figure might've been 12%. The only way of knowing that the possible figure for unobserved stations was 12%, was by not intervening and seeing what happened naturally.
General principle of you can't properly measure natural behaviour by intervening.
