As others have mentioned already, it is true that method calls on operators (e.g. processing events and snapshotting state) will not concurrently happen.
As for your findings in reading through the documentation, that might be a hint that we could add a bit more explanation mentioning this. Could you suggest where you'd probably expect to see this being mentioned, based on your readt-hrough?
