It was a pleasure, of course, to discuss this topic with you, Marvin. I know I said my previous post was the last, but as I thought about this today, I realized something else. However one might characterize the quote, I think I understand why they used it, and in a broader sense, included the commentary section of the brief.
As you are probably aware, when an appellate court hears a case, not only do the judges or justices vote on the result, but one of them is assigned to write an opinion explaining the reasoning for the result. In these opinions, some judges are inclined to include a lot of background information. This can vary from almost none to several pages. Some believe that judges are more inclined to include a lengthy background if there is a brief that contains a well-written, fair summary. So, I think this might have been a "hail mary" if you will, hoping that perhaps the judge might use some of this in the opinion, thus portraying the Watchtower's doctrine in a favorable light to consumers of judicial opinions. Ultimately the opinion contained none of this, but I think it's the most plausible explanation for including irrelevant information. The Watchtower has a long history, going back to the flag salute cases, of not only trying to win the case, but hoping to get the opinion written the way they want. (e.g., often in a way that benefits them and no one else.)
