That "tree" is really an acyclic directed graph, and because of the
one-and-only-one-path property of those graphs (there is only one way to
get to any node in the graph from the root of the tree), if you move
"leaves" like that, you're defining a different node, because it has
different ancestry.  It's not working by keyword comparison.  (Or you
could only ever have one use of "vacation" or "work" in your keyword
hierarchy...)
