Yes, but it doesn't function properly. It stretches the window across all three screens.
The only game I've dealt with so far that integrates borderless window properly and remembers window location is Dota 2.
I'm not sure what Civ V is doing but it's pretty cool that there is an alt+tab cycle where the game is still in the background and then when I click back anywhere on the screen it's instantly full screen again. Just noticed this today. It's very cool. In fact, this window with gaf open is currently on top of my "fullscreen" Civ right now.
