We study of the reliability of the Two-Step moduli stabilization in the context of type-IIB string compactifications, developing a compact manifold volume with exponential values. The general arguments are understood trough the so called factorizable models of N=1 SUGRA, where the decoupling between two field sectors is easily understood despite the lack of a mass hierarchy. It is shown that the simplified version, where the Dilaton and Complex structure are regarded as completely frozen, is a reliable SUSY description, missing only term suppressed by powers of the volume, and/or are higher order operators in the matter fields irrelevant for moduli stabilization issues. This provided the frozen fields are neutral and fixed by the leading F-flatness solutions.
