The legality is not even the point; the point is to weed out as many people as easily as possible from even trying to sue. If there's the slightest doubt as for whether you can even sue you'll be fighting on two fronts: first against the question of whether your lawsuit might be void and then the issue you're suing for itself. Lawsuits are PITA and lawsuits for the sake of just suing are doubly so. Everybody knows it. It's just logical to try to scare people off unless you subscribe to the school that tries to minimize legal hassle by not giving too many reasons for people to sue you. But still some assholes will if you operate in litigious cultures.
