Some do have stop signs before you enter, but they should always have at least an implicit yield. Vehicles entering should be prepared to stop in case there's not room to enter the roundabout yet. The real issue with their suggestion is that only being able to cross "before the entry" wouldn't get you anywhere, you have to also cross where cars exit it!
