Rielly didn't sign an offer sheet. There's a difference.
Yes, and then he's getting an average of $4m the final three. Do you think he's just going to not notice that part? You're giving him more money up front, but taking it away later. That isn't enticing. How would you feel if you were at a job, and they cut your paycheck in half as you were getting more experienced? If your entire point is to offer him money, you need to actually offer it to him. Not just at first.
I can see that you're just trying to create a situation that would screw Anaheim over, but your proposal fails on multiple levels. The biggest being that Lindholm has zero reason to sign it. You aren't offering him anything special.
Edit: The point is that you've kind of created this fantasy situation. In your goal to try to create a contract that would screw over the Ducks, you neglected to motivate Lindholm to actually sign it. You're saying that Lindholm would do it if he wants the money, but you're actually creating a situation that isn't that beneficial to Lindholm. If that was what you wanted, you'd go to 4 or 5 years, or just straight up give him max term, and more salary. The appeal here isn't really to Lindholm, it's to the team trying to offer sheet him(Winnipeg, in this case).
