It does not seem to make sense. I have no eagle but i would expect it to
work on the finished board.
One does not usually not route ground just because you make a ground
plane, usually one will route it in the normal way, just to make 100% sure
there's acceptable ground paths to everywhere, additionally to checking
the ground plane and it's connections for sanity.
There must be a parameter to specify which signal does not get isolation
from the ground plane, i was thinking it is the signal you assign to the
polygon outline in eagle.
Anyway, not having eagle at the moment, i can not believe they make a
copper pour feature that is not useful, and that can not be used as last
step in routing a layout.
