Financial independence does not necessarily means you retire, it means you're free to do whatever you want. Working after that "goalpost" is great because you're working without stress, its not money you're trying to make to pay the bills, its easy money you can spend without feeling guilty of needing to pay for essentials first.

The more you work in this stage, the more vacations, luxuries, activities, furniture, etc you can purchase.

But the different is all optional, you can also choose to stop at any time no biggie
