match method returns more points than input coordinates

[CarreauClement]

Hello,

Here's the example code

matcher = DistanceMatcher(graph, max_dist=12000, max_lattice_width=2)
coordinates = [[40.756470508651724,  -73.97319052003208]]

matcher.match(coordinates)
nodes = matcher.path_pred_onlynodes
print(len(nodes))

When I run this code I get 2 nodes while I only had one coordinate. The nodes are ['7737876085', '6452768049']

Can you explain this please ?

Thanks a lot
