The recent proposal of Almheiri et al.http://arxiv.org/abs/1411.7041,
together with the Ryu-Takayanagi formula, implies the entanglement wedge
hypothesis for certain choices of boundary subregions. This fact is derived in
the pure AdS space. A similar conclusion holds in the presence of quantum
corrections, but in a more restricted domain of applicability. We also comment
on http://arxiv.org/abs/1601.05416 and some similarities and differences with
this workComment: 13 pages, 1 figur
