  Proceeding from optical analogy we propose a new physical interpretation of
unitarity saturation leading to antishadowing as a reflective scattering. This
interpretation of antishadowing is related to the non-perturbative aspects of
strong interactions and follows from the specific property of the unitarity
saturation when elastic $S$-matrix $S(s,b)|_{b=0}\to -1$ at $s\to \infty$. The
analogy with Berry phase and experimental consequences of the proposed
interpretation as reflective scattering at the LHC and in the cosmic rays
studies are discussed.
