  Soft Collinear Effective Theory (SCET) is an effective field theory which
describes the interactions of low invariant mass jets which are highly boosted
with respect to one another. In the standard formulation of SCET, the effective
Lagrangian for collinear fields is expanded in inverse powers of the energy. At
leading order this leads to manifest decoupling of soft and collinear degrees
of freedom; however, subleading terms in the effective Lagrangian violate this
manifest decoupling. In this paper we point out that the collinear expansion in
the SCET Lagrangian is unnecessary, and that the SCET Lagrangian may instead be
written as multiple decoupled copies of QCD. The interactions between the
sectors in full QCD are reproduced in the effective theory by an external
current consisting of QCD fields coupled to Wilson lines. We illustrate this
picture with two examples: dijet production and B->X_s + gamma.
