Polyline and Polygon Intersect

Dear ArcGIS Geoprocessing community,

I would like to ask if a polyline lies on the boundary of 2 polygons, how will the intersect tool handle the output result? Will the polyline intersect both polygons or either one?

One example is a road link with residential landuse on its left and industrial landuse on its right. Will the road link intersect with the residential or the industrial polygon? Any reference link is much appreciated.

Thank you.

Joel
