Hello,
The nodes are different locations https://www.openstreetmap.org/edit?node=42491638 and https://www.openstreetmap.org/edit?node=4209145981. However when I select these nodes OSM directs me to a location that I was previously working on with JOSM, all node links will send me to this location, https://www.openstreetmap.org/edit?node=447598881#map=17/37.46755/-122.15811.
