Interesting.  I would have drawn the circles in the opposite sizes.  As 
(I think) Eric remarked, maybe Venn diagrams are not the best approach 
to explaining the effect of this new Law.

Perhaps it's easier to think of actual bridge hands.  One could ask, "Is 
there any hand the player could hold that would make the corrected bid 
but not the insufficient bid?"  If the answer is "yes," don't allow the 
penalty-free correction.  (I actually wrote that wrong-way-round the 
first time, which tells you something either about the new Law or about 
me.  To be fair, it's now after dinner, and I did have some wine with.)

Of course if you literally mean "any hand whatsoever, even one," the 
penalty-free correction will almost never be allowed.  If, on the 
contrary, you mean something looser than that, defining it will be far 
from easy.

It will be interesting to see what the DSC comes up with.
