The parallels are the best for a pairing destined to be canon. It seems that there's overload of them, but there's nothing much to do with development with NS except the moment that has yet to come that she's over Sasuke, the moment that she realizes and/or she confesses again to Naruto, the moment that Naruto will confess ( by the way one of those moments may not happen but I'm just listing the most possibles ) and one or two more which are timed specifically in the upcoming plot. Other than that there will be hints and facts like Minato's comment for example.
So, I think Kishi is doing a lot of parallels cause of that. Plus, every manga has their parallels but I think it's rare to see much parallels in manga like Naruto.
Besides... We all know that Kishi has somewhat of a fetish for parallels XD
