You are so right, haha. We had multiple fallout and multiple flow videos because they had highlighted different features of those visualizations that had been released over the course of several years. We recently re-recorded one video for each of them that covers all of the awesome feature of those visualizations, and so the redirects were set up from the old videos to the new ones. Sorry for the confusion. We will update the course as soon as possible to reflect the new videos. Thanks for noticing!
