I'd wager the human mind is incredibly more complex than we realize.

That said, I'd also say that it's possible you were actually solving the puzzle subconsciously (semi-consciously?)

Not a chance in hell. I usually don't even LOOK at the thing when playing with it. It is a total nervous keep-my-hands-busy thing. If I had not looked down when I did, I would have zoomed right through the "solved" state and never realized it.
