Hey, this question is quite old, but I also stumbled over it.
If you, like me, copied the example from the neo4j page to learn about it
WITH point({longitude: 12.78, latitude: 56.7, height: 100}) as p1, point({latitude: 56.71, longitude: 12.79, height: 100}) as p2 RETURN point.distance(p1,p2) as dist
you see, that they have mixed up the order of lats and longs in the two points, which screwed me, because I wasn't paying attention to that. So maybe you just got it wrong too and need to switch latitude and longitude.
