Is the map preview for archipelago misleading?

So fairly new player (not new, but new to DE) here. i played my first multiplayer games on the new maps today and got a game on archipelago. So in the preview picture of the map every player starts on own his island.
I know, you have to scout and stuff, but I was fairly surprised meeting me opponent on the same island than me. schouldn't that something that the preview implies because it impacts building placement, build orders etc?
