Is there a need to use inner-session async in `brochure` pages?

Please see this link for detailed overview.

I cannot find in the docs, how multiple users interact w/ individual endpoints in brochure. i see that with "each new page opens a new session" under design patter, but does that refer to client side or server side? ie a new session the server is hosting for multiple users or, every new user a new session in the server?
