Hmm, I'm not so sure about 5 either, but it'd be a little too straight forward if what you think is correct.

In 18, when one constraint is applied, the solution to the optimization problem would occur at a point in some subset of R2 (the subset would be defined by the constraint). Now when we apply another constraint, we will find the maximum within the subset defined by the intersection of the two sets given by the two constraints. Now this point was there in the set in the first case also but it was definitely less than the first maximum and that's why it wasn't a solution to the maximisation problem. I don't see any role for the modulus here.
