That line is at the top of the Q&A PDF. Nintendo always puts it there because they know how rubbish game journalism can be, so if they are going to get misquoted or comments get taken out of context, readers can at least click the link to read the source material.
The writeup by gamesindustry.biz isn't even bad, except that it's missing the link to the source. What hurts this thread here is the CaptainExplosion factor which adds its own interpretation.
Nintendo's answer to question 8 doesn't provide anything of significance. Of course Nintendo wants to increase the number of subscribers. Of course they want people to subscribe for longer than one month. Of course they'll add more value to the subscription service. But there isn't anything specific being said. Everyone can safely assume that more games will be added down the road, including games from systems other than the NES. Likewise, Nintendo will release new Switch games with online functionality. Luigi's Mansion 3 is an obvious example.
Most importantly, all of that would have happened regardless of the number of one-month-subscriptions.
