I don't have access to the reservation system right now, but assume that this is also a bulkhead. Yes, the system will try to keep a party together. SAS uses Altea theoretical seating, so it will keep you in the infant seat and the party together, but not display it to you. As mentioned above there are some legal and technical (oxygen mask) constraints they will adhere to and most probably assign you the 1AC or 1DF group of seats.
