Okay? Grab two ends and stretch them equally apart. Notice the tension in the middle? Right. Now, create some slack. The middle point gets looser. If you continue to slacken the tension you'll have none. Now, the question is, how far do we carry this analogy? Not to terribly much because embouchure are far more complex and subject to, under ideal conditions, musical stimulation not just physical machinations.
There are several variations on corner involvement. The bottom line is producing the sound that is appropriate to the style of music you're playing. The only time to actually worry about the corners is when the sound consistently desn't speak. It's either too slack or too tight. I happen to prefer my corners in a bit and if a note goes to air I adjust by remembering to keep things a bit more stable.
But see, here's the thing: by consistently pronouncing TOO or TOH I accomplish the same thing without thinking in terms of physical matters. I prefer that method.
