Spain from the Grand Campaign in multiplayer?

I've seen some people use the Spain from the Europe Campaign in multiplayer, how is that possible?

That was the only spain available when the game first came out. Once the Spainiash DLC came out CA changed the faction flag and stats. Now you can only play as the Spain with the white/red flag.

Thanks for clearing that up Tyler.
