True but whether or not they went the route they chose, they were still going to be intricately involved in each other lives because of Joseph. One couple would have been given sole custody but that doesn't mean the other couple wouldn't have been given visitation. It's not like the loser was going to disappear from Joseph's life. Also, custody arrangements can be challenged so just because one side was granted sole custody doesn't mean the other side couldn't petition again in the future. At the end of the day, noncustodial parent was still going to be around and those couples were still going to be involved with each other.
