Query:

Does balkanized government code imply in all cases a series of different, separate governments?

Why do I ask... well, I'm glad you asked (you were going to, even if you didn't know it)...

So let's say we have a normal balkanized world and then they have some nasty wars and come close to the sort of war that leaves nobody to write the victory dramas.

Then, in a decade or five of picking up the pieces, they kind of realize that despite their differences, they need to have a body to work on international issues, to prevent large scale conflicts and eventually it adds some aspects of world government to it.

That said, the countries are not merged, they just all contribute members to a ruling council. The council's will carries the days (majority rules, 2/3rds in some particular areas) but there may be some limited 'Notwithstanding' clauses. But they work like the EU Parliament. There are plenty of national politicians in each of the polities on the world that contribute members to the ruling council.

So what type of government is that?

Balkanized?

Charismatic Oligarchy or Non-Charismatic Oligarchy?

I don't feel like it is an Impersonal Bureaucracy.
