The difference is that from 3rd POV it is deterministic... POV plays a role. So as I said to you before, be consistent and reject MWI. If you accept assigning a probability of seeing spin up/down before measuring, you should accept the same for Bruno's thought experiment, or you must reject both, or look like a fool.
