Like others, I cannot tell you whether separation was lost between the aircraft you were travelling on and another but I would point out that there are situations (admitedly not a huge number) where visual separation can be used. The 5 miles/1000 ft separation is a minimum in some situations, but there are many other legitimate separations that might result in aircraft being a lot closer together - completely safely, I might add.
