They are completely separate websites. :)
Btw, If you do only step 2 and step 4, you can get a fully working DTube clone (without scot). DTube is a static app and easy to host anywhere.
You can even download the https://github.com/dtube/production and just open the index.html from your pc... it should work. Maybe you'll need to click the logo to get the homepage to display but then everything should work.
