It does look visually similar but I'm not convinced. I did suppose that Hal was likely Satoshi and this makes it even a bit more likely.

Yeah. zero chance that was accidental. Either Hal did it and was Satoshi, or if Hal's not Satoshi, it was someone else leaving high quality clues to create a fog of false leads that point to plausible suspects. That's where I landed. I am just convinced that this was not accidental and is too close to not have been intended to mean what it visually and audibly decrypts to represent.
