Quite a clever little hack to save memory, yes the shp file suffers
from a lack of accuracy, but so does the geolocation input data.  One
reason I like the Gnome proposal to use spatialite to do proper
geoprocesing is you can assign a buffer function to all borders and if
you fall within the buffer then ask the user to make a choice, or try
use some other heuristic to help decide.
