Either that information is wrong and only the lvl 80 one counts, or the information is correct and any quest counts, but you're required to do the quest while also being on the MSQ for the item to drop.
It's a bit misleading. They want you to complete at least one of the role quest chains that starts at the Crystarium. But by the time you get to that point, the next quest in the chain might not be at the Crystarium, but you stil need to complete it as it is part of that quest chain (even if it's level 80).
