Depends, perhaps, on what the meaning of KNOT is. . . .
If the plywood has exterior glue, seems to me the glue is providing a moisture barrier, while the wood provides a "condensing" surface. If the seam joints were caulked or sealed, how would the interior conditioned space know whether there was "building paper" or "tyvek" or even cladding on the exterior? I believe the origin of building paper was to keep the "wind" out more than the water.
In any case, here in the Pacific Northwest, we build a lot of houses in the rain and cover them with plywood. And if you are on the "inside", you do not get wet.
