You can't trust these videos to show realistic placement of districts/wonders. For example, in this Kongo video https://www.youtube.com/watch?v=hvtvjo3fPsQ around ~1:30 we see that Big Ben is not placed next to a Commercial Hub, even though as far as we know it is required to be.
They use "world-builders" to make these videos that probably ignore placement requirements.
