Its all fairly pointless for now though, 1st and 2nd level is all you really need up to 100nl anyway.
I think you're probly correct here but I would def like to get some other players opinions who are playing at higher stakes.

If we go down a level in thinking without knowing what level our opponent is thinking on then doesn't that give him a chance to make the correcy play even though he is thinking on the wrong level?

An example would be from the AT/JJ HU hand above. Let's say we go back to level 0 and simply raise our pair of aces for value without considering what he has and what he is thinking about. Well, he may think that your bet looks bluffy given his c-bet range, and the dry board. But he also may think that you know it will look this way to him and so you wouldn't make this bet with air. Therefore, he may fold, which is not at all the result you wanted.
