The problem with that "rule" is that it doesn't work. People make those ill-advised contacts (or accept them) believing that there IS a good reason for it, that it won't wind up making them feel bad, that it won't hurt anything. It's just like the rationales alcoholics have for having a drink. This one won't hurt, I'm in control, yadayada.
By the time "no contact" is needed, we are often pretty poor judges of what contacts will be helpful or harmful. Thus, avoiding ALL contact is often the safest, sanest course to avoid being sucked into those bad situations.
