  The high energy evolution equations that describe the evolution of hadronic
amplitudes with energy are derived assuming eikonal interaction of the evolved
hadronic wave function with the target. In this note we remark that this
derivation allows a different interpretation, whereby the hadronic wave
function is not evolved, but instead the evolution acts on the S - matrix
operator. In this approach, analogous to the Heisenberg picture of Quantum
mechanics, the scattering is not eikonal and additional boost provides for
radiation of more gluons in the final state.
