  In this paper, we show (i) that the NLO corrections do not change the
power-like decrease of the scattering amplitude at large impact parameter ($b^2
\,>\,r^2 \exp\left( 2\bar(\alpha}_S \eta(1 + 4 \bar{\alpha}_S)\right)$, where
$r$ denotes the size of scattering dipole and $\eta\,=\,\ln(1/x_{Bj})$ for
DIS), and, therefore, they do not resolve the inconsistency with unitarity; and
(ii) they lead to an oscillating behaviour of the scattering amplitude atlarge
$b$, in direct contradiction with the unitarity constraints.
  However, from the more practical point of view, the NLO estimates give a
faster decrease of the scattering amplitude as a function of $b$, and could be
very useful for description of the experimental data. It turns out, that in a
limited range of $b$, the NLO corrections generates the fast decrease of the
scattering amplitude with $b$, which can be parameterized as $N\,
\propto\,\exp( -\,\mu\,b)$ with $\mu\,\propto \,1/r$ in accord with the
numerical estimates in Ref.[1].
