The dock is a charging cradle if nothing else. So if both you and brothers' Switch are dead battery at same time,
and you both want to play Switch multiplayer on TV at same time, you need 2nd dock to recharge other Switch.
Many families also have multiple TVs in their house. If you don't, then just leave 2nd dock in a closet for recharging use.
People hyped up the dock when they thought (based on patent applications) that it would hold 2nd CPU, GPU, RAM.
We now know it holds nothing of the sort, so there is nothing of substance that you are paying for beyond charging cradle.
And like every other electronic device that COULD use the charger of another device, they will be sold with charger included.
