  We demonstrate that the diffraction slope of the generalized BFKL pomeron
amplitude has the conventional Regge growth $B(s) = B(0) +
2\alpha_{\Pom}'\log(s)$. This proves that the generalized BFKL pomeron is
described by the moving $j$-plane singularity. We give an estimate for the
slope $\alpha_{\Pom}'$ in terms of the correlation radius for the perturbative
gluons.
