The point is still valid. Within the scope of a single request, only
one thread will access it at a time, but there is no guarantee the next
request to that page will use the same thread.

According to Igor, the 3 bullet item is not valid, or at least this

that a request is guaranteed to be served by only one thread and the
synchronization done, it looks
like a page will be accessed by 1 and only 1 thread per request.
