Using the URL bar will only ever download the one video that the link URL applies to. So with this playlist, every time a new video starts it will have a different URL.
Unfortunately the URL bar has not been built for any kind of continuation, and so is not suitable for getting entire playlists. Even if it could, doing it that way to get an entire playlist of that length and size would probably take a good long while because it is a bit slower than the normal stream capture downloading and the videos you are wanting to download are quite long.
I would recommend using the normal stream capture method for this. If you start the first video then the capturing will begin automatically, and then you can either walk away and let the playlist run through normally and capture each file as it comes on, or you can click on the next video almost immediately after the current one starts. The second approach would be the fastest, as you don't have to let a video play through or even keep it playing in order to capture it - it only needs to be started. Downloads can also be done simultaneously, so you could just click through all the items and add them to the download queue and then leave it to finish.
