Look, I'm just poiting out what he said in some of those interviews. You probably got a mistranslation if you think he said that "NH never crossed his mind" or "Sakura would be mean to Hinata". He said that Sakura would be a terrible woman if she moved on from Sasuke. And he never said anything about NH not being planned. Only The Last.
No those sentences you used were outdated sentences that were re-translated by people who weren't NH fans. Yes he did say he didn't think about NH and yes he was referring to being cruel to Hinata when talking about why NS didn't become canon
