loads of all pages loaded during visits where the "contact" page has been loaded.
let's imagine a site that has received 3 visits over a given period, made by three different visitors: a, b and c. these three visitors have loaded four pages: home, product page, contact and career.
we will now show the difference between a filter applied on the "contact" page and a segment based on the "contact" page.
comment: this filter will only focus on the "contact" page. the other pages have been removed.
comment: this time, we get page loads for all pages loaded during visits where the "contact" page has been loaded (visits b and c).
