Official source text from the 1 February 2010 Rules release
If an object has an ability printed on it that causes a player to "choose a [value]" or "name a card," and another ability printed on it that refers to "the chosen [value]," "the last chosen [value]," or "the named card," these abilities are linked. The second ability refers only to a choice made as a result of the first ability.
