I think I understand what he means. I know all of you won't agree on that, but I think counting love as an aim for Naruto that was part of his nindo of never giving up was wrong. Love was never a big deal for Naruto. The Promise of a Life Time and Sai confessing Naruto's love was just for drama purpose and also leading to NS death with the fake confession that put an end to NS.
Also this interview shows that every shippers were somehow right in their interpretation: NH/SS were right for their interpretation from at least Pain Arc while NS were right for their interpretation of the beginning of Part 2 until Pain Arc. I think Kishi wasn't sure on which couple he wanted in Part 1 thus leading him to give hints and moments to every ship. He wasn't very invested in romance in Part 1.
Let's assume this is right.
Let's assume NS died around 470.
If NS died way back then, then what was the point in
- paralleling Naruto saving Sakura like Minato saved Kushina?
- Kushina telling Naruto in 504 that she wanted him to fight a woman like her, which was confirmed to be Sakura in 631?
- in the majority of Sakura's panels being dedicated to Naruto?
- Road to Ninja, which clearly paralleled the kitten out of MinaKushi?
Kishimoto is full of kitten.
He's backtracking from the pairing he developed to validate pairings that were set up to fail but didn't because they were popular and therefore lucrative.
