  Quantum-reduced loop gravity is a model of loop quantum gravity, which - from
the technical point of view - is characterized by the remarkably simple form of
its basic operators. In this article we examine the operators of the
quantum-reduced model from the perspective of full loop quantum gravity. We
show that, in spite of their simplicity, the operators of the quantum-reduced
model are simply the operators of the full theory acting on states in the
Hilbert space of the quantum-reduced model. The passage from the full theory
operators to the "reduced" operators simply consists of noting that the states
of the quantum-reduced model are assumed to carry large spin quantum numbers,
and discarding terms which are of lower than leading order in $j$. Our findings
clarify the relation between the quantum-reduced model and full loop quantum
gravity, and strengthen the technical foundations on which the kinematical
structure of the quantum-reduced model is based.
