Thanks for the answer, now it's clear how it works.

But there are still 2 teams in it)

And yes, I installed it on two servers, and did not notice the difference) Since I have a Chatty plugin that works with bungeecord, and redirects messages to all servers, but thanks for the clarification

It's easy, but it's not easy at all!

Installed
Rebooted the server
View his only 2 teams
I tried to use them

Nothing happened

Removed the plugin

Wow, works great! Good description here, it really helped me understand how it works, well done!
