Within the model of uncorrelated scatterers and a long mean free path the recently proposed structure of the density matrix in a current‐carrying state is shown to be produced and reproduced by the superposition of all scattered waves. The corresponding transport length corresponds to its classical value, but the physical picture is a new one.
