Too X that vs so X that

In a comment, John Lawler wrote:

Too is a negative. Too high means so high that Not S, where S is some expected result. Too doesn't take a that complement clause. But so does. The idiom is so Adj that S or such (a) NP that S. So and such mean the same but work with different kinds of words. So it's probly a mistake, with somebody typing too instead of so, the way they might type to instead of too.
