Thanks for reaching out!

The example you provided is linking against GraphHopper maps. The route found by openrouteservice is different and AFAIU the actually desired one, please compare https://classic-maps.openrouteservice.org/directions?n1=51.005987&n2=3.753424&n3=18&a=51.00548,3.75558,51.0065,3.75131&b=0&c=0&k1=en-US&k2=km.
