Match service: Leg ending and beginning is overlapping #6722

Hi there,

We are struggling with interpreting the legs in the output from OSRM. Our goal is generally to draw a line with timestamps for each node. To draw the line, matchings[i].geometry.coordinates should be enough. However in order to enrich the coordinates with timestamps we need to use the legs.

I looks like that in a leg with n nodes, there is n-1 distances and durations. I guess duration[0] is the duration between nodes[0] and nodes[1]. However, we have noticed an overlap between the ending of one leg and the beginning of the next one. It appears as though the last two nodes in a leg also appears in the beginning of the next leg. Why is the output like that and how should the distance and duration be calculated in the overlap?
