Tell me if I get this correct:

Alice visit a site and gets the hash 1234. The analytics data is stored and associated with hash 1234, but soon after, hash 1234 is removed. However the aggregate visitor analytic that was associated with hash 1234 data persists. Then another user (say Alice again) returns and gets hash 5678. Analytic data is tracked, stored with hash 5678 for the 30 minutes (or less), and then hash 5678 is again removed. However the analytic data that was associated with 5678 is aggregated with the rest?

That's exactly how it works. The purpose being to make it completely impossible to ever single out a user and see which pages they viewed on a website.
