Newb question on GameStateNodes

I'm planning to change all of my current basicGameStates to BasicGameStateNode. Does GameStateManager which is an extension of GameStateNode synchronize update instead of running several separate updates together

Or would it be better to use BasicGameStateNode; however for some odd reason I still have to attach each BasicGameState to the GameStateManager… I'm using StandardGame would this be a reason…

You attach GameStates to a GameStateNode, and the root GamesSateNode to the GameStateManager
