GRASS "layers" in a GRASS "vector map" have *common geometry*. You can't
edit the geometry of one GRASS "layer" not interfering with the
geometry of the other "layer" in a single "vector map".

This is different than in case of e.g. shapefiles, where each layer is a
set of files dedicated only to a particular layer, thus when you edit
it, you do so only for this particular layer.

GRASS "layers" and OGR "layers" are different things.
