It was a double entendre, you got the NIS joke, you win the internet for today.
Since we're apparently going into an era where the big game companies are just gobbling up everybody else, this would be a bona fide good investment for both companies. NIS was really struggling just a few years ago, but they've made enough money on the Switch to where they're able to be the US licensee for a lot of smaller Japanese studios like Falcom. That's why NIS goes through the trouble of porting Falcom games to Switch. And Nintendo can always stand to bring more good content into its stable.
