Confusion with the code used in one of your video

In one of your video(Video 28) you guys have mentioned that when negate sign is used with takeOrdered(), we get values in ascending order. But when I demonstrated the same scenario I found values in descending order.
Even your output was in descending order but it was not corrected anywhere in the video. could you pls clear the concept, so that we are not left with any doubts by d end of the session.
Below is the link of video I reffered to:

Table PATH used: /public/retail_db/products
I am attaching my output as per you code.

Also when I removed the negate sign my output was in ascending order. so basically clarify that why negate sign was used.
