As you know the suit compresses more the deeper it is losing more and more bouyancy. At some point the loss of bouyancy no longer increases, the suit is effectively at maximum compression. By doing the test in the pool and the protected ocean area you know if you are safe when the suit is maximally compressed. If you are safe there, you are safe shallower.

If your positive at the end of the dive and need to do deco you will not be able to.
