If i understand correctly, the fall back server serves a fail proof, so if a server crashes, or goes offline players are just moved into the fallback server rather then logged off from the server. If that is correct, i'm having issues with mine and not sure why, when a server goes down it just logs off all the players from that server rather then sending them to the fallback server. See below for my config:
