Django corrects the slalom

In slalom, the dog has to circumvent all the sticks of slalom. When he misses and we will go to the next obstacle withput correcting the slalom, we would be disqulified from the actual run. At our training, Django missed the last stick and I failed to notice it and I wanted to send him to the next obsatcle. Django disobeyed and went back to the slalom, to exactly that stick which he had missed, corrected it, and continued to the next obstacle. I am sure now that he counts the sticks of the slalom. Here is the video, slowed down his correcting movement.
