actually that part is vague. Kishimoto just said that "Sakura would be a terrible woman if she has a change of heart for Naruto". Kishimoto isn't talking about Sakura's being hesitant on Naruto/Sasuke. He was hesitant on making NH or NS as the endgame couple.
Anyway, it's obvious that he made Sakura to develop romantic feelings for Naruto in the story. It's something that has everyone's eyes on one. And who deny it he is just blind
Hear hear
