Oh that, the actual Hakumen (thus also the Susano'o Unit) is still in the Edge (the sub-space between the World and the Boundary, but technically still part of the World). The thing that currently walks upon the world is more of Hakumen's phantom/image/projection that is recognized/observed as the real, tangible thing.

In Hakumen's case, in one of the timelines/worlds during CT, he basically projected his own will upon the World and recognized/observed it as the real thing, as himself, although he had to overcome his own ego to do that in that instance (otherwise his own will of the observed one would have interfered with the one doing the observation, I guess :P ? Kind of like when Kokonoe tried to interfere him during his duel with Ragna, but Hakumen managed to overcome it).

Observing oneself does sound kind of impossible, which of course is also Ragna's reaction when he hears that, but Rachel affirms it by saying that if someone could do it, it would be Terumi. Of course, it's not something that can be endlessly/continuously done by oneself in the long run.

Some of the things that are (or embody) a contradiction, have to be observed (either by themselves or someone else), otherwise they wouldn't be able to work/affect the World or even disappear.

Those that can affect the World from the Edge can be pretty much considered as Demi-Gods (the Susano'os), while those that can influence the whole World(s) from the Boundary itself, could or rather are, considered as Gods (like the Master Unit and the Takamagahara).
