Ok, yes, in the case where you have to have all information on one page. Another way is of course to get that information in a ajax call, or open a SSE/Websocket connection to listen for events from the event bus. But there are of course cases where that's not feasible.
And in the case of auth systems what we typically do is to have a separate app for logins/authentication, then do simple SSO or domain cookie sharing and let each sub system handle the authorization.
My point is that not all SOA has to be as complicated as the article's. But if you go that way, yes, then all your points apply.
