Achievements like these have been dubbed "platinum" achievements because what happened is the PS3's trophy system now gives platinum trophies for getting all other trophies. It's an incentive to 100% a game as is the way 360 has a tab listing specifically for games in which all achievements have been earned. And then lazy developers who release on both systems don't take that platinum trophy out and it gets published as an achievement.
Other games that have platinum achievements that I know about:
Dynasty Warriors: StrikeForce
