A question has arisen over my use of this term. To my knowledge, this is a traditional Lutheran term to distinguish the Lutheran position from the Catholic.
A more complete statement of the Lutheran position would be explicate the real presence in terms of a sacramental union (unio sacramentalis) between the communion elements and the true body and blood of Christ, which has its conceptual parallel and metaphysical embedment in the finer points of Lutheran Christology (the unio personalis or hypostatic union).
My immediate point is that you cannot derive this interpretation from a "plain" reading of the words of institution. This is, rather, a theological construct with quite a lot feeding into it. That doesn't make it wrong, but it does invalidate simplistic prooftexting.
