We identify the correct power counting of all the variables in the low-q2 window of the inclusive decay B‾→Xs within the effective theory SCET if a hadronic mass cut is imposed. Furthermore we analyse the resolved power corrections at the order 1/mb in a systematic way. The resolved contributions – as a special feature – stay nonlocal when the hadronic mass cut is released. Thus, they represent an irreducible uncertainty independent of the hadronic mass cut.
