All the accounts and posts can communicate/share across the instances, but each instance has its own database of posts.
The example people give is that is like email. You can have licenensedtoill@gmail but you can send messages someone @yahoo.
You dont have to create a seperate account for each instance. And on whatever instance youre on you can browse and post on communities of any other instance.
Theres definitely some work to be done to make this all more intuitive though

Does that mean someone else can have the same username as me on a separate instance?
Yes, just like with email.
