Well, it's an interesting point, because apparently if the tape recorder never turns back on, you're just kinda stuck in time as the person you were. So it suggests at the least that the tape recorder aspect of consciousness, perhaps in the way it feeds back one's perception of oneself to oneself, is crucial in the sort of consciousness we humans see as critical to identity.
Clearly though, this guy is still "conscious" - it seems like a situation we don't have quite the correct terminology to describe.
It's sort of a weak version of a P-zombie. Presumably the lack of conscious awareness would still be observable using a sufficiently detailed brain scan if not anything else, as opposed to a "real" P-zombie where the presence of consciousness is assumed to be completely epiphenomenal.
It's not that we're not aware, it's essentially that we may only be aware - aware of our thoughts once our subconscious thinks them, aware of our actions and their consequences once they're made.
The trick, seemingly is manipulating the focus of awareness to convince the subconscious decision-making apparatus to make different decisions, even though all we really have control of is our awareness.
Yes, this is the "weak" position. The original definition of a P-zombie is an entity that really does have no qualia, that is, subjective experience or "consciousness", but behaves exactly like it did, down to the neuronal level. It is a thought experiment and can be used as a reductio ad absurdum to argue that eg. uploads still have qualia.
