I think it proves nothing. My guess is the dots were put in the same order, creating a picture the bees could memorize. 2 or 4 dots means nothing. the pattern they are in makes a design the bees come to recognize. Change the dots to X's halfway down the trail, or take the dots out of a straight line and make a square with them, and the bees will become confused and lose their way. It has nothing to do with counting.
