It might be in a situation that someone mentions a group of members(成員), then you would immediately think of a team(組合) related to these members. For example, when you talk about, Katō Rena, Gotou Moe, then you will reply 'Oh it can only be AKB48' But it does depend on the situation~It will help if you provide more information.

emmm I thought it must want to express that this combination style is suit those members?
