Indeed --- Human relations are complex and unpredictable, and the same goes for political relations among nations. Negotiating a new treaty or agrement is complicated enough. If everything was set in stone, no treaty would be of any use after a couple of years, since everything changes. That is why, I think, ambiguous language is prefered and then someone is assigned to clarify issues when they arise on a case by case basis.
