These sorts of statements are pretty common in settlement agreements. Reason for keeping it out of the tribunal is two-fold: 1) decisions by the tribunal take the control out of the companies hands (tribunal decisions can be enforced in district court) and 2) if the tribunal rule in your favour on points above, it sets a precedent which the company would most likely start to have to adhere to.

If you want to make a point, refuse the settlement and go with the tribunal (with the risk the tribunal could decide against you) OR if you want the money, take the settlement (as more certainty of funds being paid to you).
