Pride and Prejudice Film Mistakes

Usually I am so absorbed watching a film that I fail to catch any but the most egregious mistakes. But some people are ever vigilant. This list of movie mistakes notes that 16 were made during the filming of Pride and Prejudice. Here is the link to the site.

Here is one of the observations:

"Continuity: In the scene at Pemberley when Darcy gets ready to dive into the pond, notice that in one shot, he is looking at the pond, the next shot shows him stepping down, and the third shot (right before he dives) shows him looking at the pond again - in the exact same place as the first shot, as if he never took the step down."

I can't see what this critic is talking about. Can you? Or do I need new glasses. After watching the first 4o seconds of the film clip, do you agree or disagree with the above statement?
