I don't know if I asked question correctly. I will show an example:
1. on VB without "helpful" scripts, if user wants to add a topic he clicks add topic he adds topic and then he gets redirected.
2. XF shows posting options on the same page as he is reading and adding a topic on the same session?
1. 3 page views (1 loaded website + 1 redirected to new topic page + redirected to added topic)
2. 1 page view (all done on same page without reloading and redirections?)
If you scroll down forums can show you next page as a continuation, you don't have to click next site. It is super convenient but do you get all page views as you would get from all the clicks through on "next page"?
