Yes. That's exactly how that works.
Bezos obviously isn't hiring slackey accountants. He has the money to hire the best people to manage his wealth and direct how to oversee every aspect of his business and personal assets. Likely an entire team just for that.
I can't imagine how many people he has on his payroll to manage his life. EA’s and PA's to manage his schedules, people to manage his properties and yacht, publicist, personal trainers, chefs... Does he even bother with having laundry done or does he just throw stuff like underwear away and buy new?
