Confused with SW2

It "already" happened in Civil War (the establishment of the New Empire headed by Astra). The confusion stems from how the games were renamed. The original games apparently ignore Star Wolves 2; the english versions count that one that's why our Civil War is Star Wolves 3.

Peek into the music files and you'll see them with their original Star Wolves 2 Civil War tag, even though the game intro screen tells us this is Star Wolves 3.
