That interview talks about stuff around the Chunin exams. It's well known that half the iconic Naruto stuff was pretty much coincidental. Sasuke wasn't even in Kishimoto's original plan. That doesn't mean it's true for everything. It's clear from things like Hiruzen's memories as well as cases like Obito/Tobi, as well as Itachi as mentioned in that very interview, that Kishimoto did in fact plan things.
