I believe they would cut to leave everything inside the line (within the tolerance). For PCB Express I draw a 1mil copper on the top layer to indicate the cut line. They require 10mils from the edge to the copper. IIRC the V-scoring at Advanced circuits produces a V that is no more than 30mils wide and they recommend copper no closer than 25mils to the edge. For boards with edge mounted connectors my goal is >=25mils from the edge. For a Micro-USB and micro toggle switch I have gone down to around 10-15mils. For everything else I will do 50mils. 50mils from edge and 50mils between designs on a panel enables me to cut the boards apart with a hacksaw with minimal cutting.
