If I am reading your example above correctly, "value" is synchronous, so it would never know if someone else has incremented it? So reading it client side will be wrong the moment someone else adds it.

The backend is stateless, so in the example, the counter is unique for each user. To share the counter among all users, the backend must save it in a database.

And again, I ask how the UI gets to know that it has changed.

When you execute a remote method on an object, the attributes of the object are automatically transported between the frontend and the backend. So, when you change an attribute in the backend, the change is reflected in the frontend.
