Does the node order in the incomingEdge indicates the real heading of an edge?

e.g when I print a state object, it shows “State{closest node=132980 at 31.04679312316358,121.41116847778764, incomingEdge=132980->14413, outgoingEdge=132980->23582}”. Here, incomingEdge should be an edge from node 14413 to 132980, but it is reverse, why?
