This case cannot consider "how bad the defense was" against an illegal contract. After the infraction during the auction is remedied, the subsequent illegal call(s) cease to exist. They are certainly not reinstated for the purpose of penalizing the NOS for their bad defense.
This is not quite the case. The reasoning goes something like this...
Suppose that opponents, through some abuse of UI, reach 6NT (say there is a slow response to blackwood and opponents then choose to bid on when no logical person would do so off two aces). I am on lead with two aces. I lead one ace, then continue that suit. Eventually the contract makes.
Certainly if opponents had not abused UI, they would not have been in 6NT, and I would not have had the opportunity to let them score up 990. But come on! Their unethical bidding landed them in the soup, all I had to do was lead my aces and I was winning many IMPs! How is it fair that I pay no penalty for my idiotic defense on this hand? Certainly if I had lead my aces and set them a trick, the director would not then rule the contract back to five-making-five because "if the opponents had not abused UI, they would only be in five and I would not have had the opportunity to defeat them."
If the laws were interpreted as you suggest, then it would be to my advantage to take certain crazy actions when opponents may have abused UI. For example, suppose that opponents bid to game in an uncontested hesitation auction. I might as well double. If the game goes down then I win more by doubling. If the game makes then I will call the director and complain that opponents would not have gotten to game without the UI. This is what's called a "double shot" and is not allowed -- I have to continue to play "normal bridge" in order to get my adjusted result.
