It's probably a coincidence: Balance of the Force was a very popularized rumored name in 1997/1998. Which is why "Phantom Menace" suckerpunched a lot of people when it was announced. Everyone assumed "Balance of the Force" was the title. And "The Clone War" was not only the title of a videogame that had been released BEFORE "Battlefront" but was one of the most rumored names for "Episode II from even before Episode I was released. The same idea that jumped into Mags head regarding titles has probably jumped into a lot of people's heads. I even remember Spin magazine, back in 1999, saying "The Clone War" was definitely going to be the title of Episode II, so the idea of that being a title in the Star Wars universe has been around for quite a long time.
