Ok. It's only a troll if you let yourself believe a character's feelings can change off-paneled. You must wait for them to say it or even talk about it one last time. Pretty much, NH got what some if not most NS fans got from 540, thinking he/she is over with his/her old love interest. That said here's a problem that 631 got over 540.
First of all, 540 is not needed if we already acknowledged that she loves Sasuke. So why is it needed? Because there's a chance of a follow-up to it. 540 while it may seem bad for many, in reality, this could backfire heavily as well. Sakura thought of him in a very negative light, which is also the first time being questioned if her love is really good or not, and it's not. Not to mention this is after she still have hope for Team 7 happy ending. While she can be hopeful on that, her love is a different story and she knows that it's not really good as she just may realized it. So this needs a follow-up and left unanswered.
Now, we look at 631. First off, Sakura was the one who Minato asked if she's Naruto's girlfriend, yet Naruto replied it for her. This confirms his feelings for her and if it didn't, then the last page really did. What's the problem? There's no follow-up because that WAS the follow-up. Naruto sees his love aspect positive, nothing like how Sakura thought of Sasuke. So it's sealed by Minato as well as Naruto. To make matter worse, Naruto reconfirmed his feelings AFTER Hinata has done many things that she wished and Sakura is getting hers with a bonus of the fact Team 7 is back. Lastly, this volume is favoring more to Naruto, so he will come out at the very top when it's all over, and if you remember Pain Arc ending, well you get the picture. ;)
So yes, 540 needs a follow-up to see if there's anything to go with that. That said NS is growing too strong since 629 and it will only go up. The last question is if this is the end of NS moments in this volume only? We shall see.
Have you noticed...every arc ending that has a Naruto/Sakura connection ends up more intensive.
Every arc that ends with them together, Sakura feelings for Naruto get stronger, and as I noticed it is a linear progress.
It went from Acknowledgment, friendship, before progressing even further. To offer to feed him, comforting him after Jiraiya's death, crying for him to show up after Pain had destroyed the village, hugging him in front of everyone, realizing what was already in her face...that he just didn't have a crush on her...he clearly loved her, she wanting to give up her happiness so that they could be together [this is real love]...before he refused to saying he rather not give up her happiness so he could be happy. [the correct response]. If you noticed the linear progression it goes from Crush, love, hug, and then confession...fellow NS'ers what usually comes after mutual confessions?
