I’m not sure I get the manipulation rules mentioned in the Gonzalo Frasca reading (See here).

On page 231, Frasca talks about how, “… these rules are opposed to the goal rules in that they do not imply a winning scenario.” I’m not sure what that means. I understood manipulation rules as being another way to reach a goal using a different set of rules. But from what I understand in this quote,  these rules are different from the rules to achieve the goal, and that it usually ensures failure?
