With the adopted approximation the model considered as a parcticular solution of the triple pomeron decoupling problem. Explicit forms of such a coupling and a qualitative comparison with the experimental data on single DD are presented. The modified factorization properties of the model are also discussed.Talk given at the XII-th workshop on "soft" physics "HADRONS-96: CONFINENENT" Novy Svet, Crimea, Ukraine, June 9-16, LaTeX, 8 pages, 4 eps figures includedHigh Energy Physics - Phenomenologytext
