Correct.
Because all the URI above says is that there is a node with an
ID 1381574156. It does not say anything about a physical object at all.
And that is a good thing, because actually the node is only a point on a
map.
Now if this node (point on a map) is replaced with another one by a
fellow mapper (for whatever reason), I think it would be a progress if
ID 1381574156 points to the new node instead of vanishing.
This has absolutely nothing to do with physical objects or OSM to be a
database of things.
