It would not have to be wired as a true wye if there is no connection between the two legs at the top of the wye, so that trains would need to go into the leg from either direction before they could continue on to the other leg of the layout. The problem is that any train going into the island would have to back out of it, and then they would probably have to back the rest of the way to the end of the layout before the locomotive could turn on the turn table.
