When people that act the same, hang out together. People that have the same morals often tend to group. It has nothing to do with jealousy, nor the amount of friends a person is allowed to hang out with. It is NOT pointed towards having a close friend neither. it simply means when people act the same, they normally hang out. Like a clique.
