OK, I think I got it. You're saying that, for a Realm, the global object never changes, but that the (initial values) of 'window', 'self', 'document'(??) etc. are proxies (all the same one?) whose target can dynamically change. So, yes, that seems to explain things. It also means that Anne's original question about "replacing the global" object seems to be relevant as the actual global object binding never changes.
