Sounds like there could have been communication mix-up in that interview. (Or, worst case scenario, Nao's just a big old liar.)
Yuuki Ono was the main suit actress -- she's done ton of interviews about it, it's well known. That interview just makes Nao sound like she's taking all of the credit -- when, giving her the benefit of doubt, she's thinking about those open-visor scenes, which doesn't make her the suit actress, especially since all three of them opened their visors like that and never did any action when their face was seen.
The only actors who did their own stuff in-suit -- Kenji Ohba, Jun'ichi Haruta, Koji Unoki. And these three are JAC guys, not 17 year old idols. How can anyone really think a 17 year old idol would really be doing the action?
I'm sure both Yuuki Ono and Nagasawa Nao were the suit actresses for Hurricane Blue. It isn't uncommon to have multiple actors for the same character. Also, it seems that Nao has a martial arts background so even if she is not a trained stunt actress, at least she can do a few moves in the suit without looking like an idiot.
