It is shown that three-body models of inclusive inelastic break-up ('break-up fusion', BF), lead to an ambiguity also known in the DWBA description. The use of two formally equivalent representations of the break-up transition amplitude can lead to manifestly different expressions for the BF cross section. The cause of the ambiguity is traced to the many-body effects which are ignored in the three-body model.
