I would argue that it would be better for the kids to live abroad. They'd become bilingual for free, and most importantly it'd give them perspective and a better understanding of the world.

Unless his kids are planning to become professional American football or lacrosse players, his justification seems very weak to me.

The guy was born in Brazil, lived there till five, moved to the US, then lived in Brazil for two years as a missionary, and is now doing business there. He probably has a pretty good idea of how beneficial living in Brazil would be for his family.

He's also very wealthy and can afford to give all his kids personal language tutors if he/they want to learn another language. The value of knowing Portuguese in the US is generally not that high (although obviously he's an outlier). They can travel internationally whenever they want. If they moved there, they wouldn't be living or going to school with your average Brazilian, they'd be living in a wealthy neighborhood and going to an English-language international school. They live in one of the wealthiest places in the US, so they probably attend very good schools right now.

Since they're Mormon, many of these kids will end up being missionaries in foreign countries and learning another language anyway and getting a decent perspective on the world outside Connecticut since their living environment as a missionary will be roughly equivalent to the average person wherever they're assigned.

Don't underestimate the importance of high school sports to kids that love them and are in high school. I'd rather my kids have four years of positive team sporting experience than learn Portuguese. One can learn and grow from sports in many ways even if they don't become a professional athlete.

As for what will best help their career, it's probably the stable familiar living environment they currently have at a private school that will best prepare them to get into a good college and do well there. Being good at sports doesn't hurt either for getting into good colleges.

Finally, he can easily sleep in first class for the two direct flights he takes per week and he can spend (potentially, we don't know how much he works on the weekends) Thursday (not sure how much of the day), Friday, Saturday, and Sunday with his family. He can also potentially video conference with them every other evening. And they've probably come with him on occasion.
