As an actual lawyer, sorry to say that you're wrong. A settlement means that the facts are never adjudicated. In the eyes of the law, NGN has not admitted to any wrongdoing. NGN is not "the loser" and Harry is not "the winner." Unless a settlement includes some form of injunctive relief (I.e., a legal directive requiring one or both of the parties to either perform or refrain from performing some specific action), the settlement is nothing more than the parties' joint agreement to stop litigating the case.
So legally, yes, Harry did, in fact, walk away. So did NGN.
