I hope you are not trying to raise the hope of financial compensation for any JW survivors of Nazi persecution. The financial compensation for Jews in regards to Nazi persecution was time-limited, and has long closed. The provisions for compensation were enacted by individual governments (Austria, etc.), and any action by the Swiss would have been only one of a number.
The Nazis, being German, kept detailed records of their victims. For example, the book dealing with JWs in Auschwitz (available from Auschwitz museum) includes details such as photos of JWs. The Nazis kept so many records that they cover many kilometres of files at Bad Arolsen in Germany, initially administered by the International Red Cross. From the details kept by the Nazis, I was able to know the dates my grandparents were transported from Vienna and the dates of their murders.
The text suggests the WTS was making a corporate grab for money, without having evidence or having experienced the horrors of the Shoah. ("If the court sees fit to allocate a portion of the settlement fund to the Watch Tower to continue this work of remembrance.")
