This makes the most sense to me. A path, to paraphrase John, is
nothing more than directions to a location in a tree. Whether the
directions lead to a leaf or not depends on the "context" i.e. on the
tree that's being traversed. So, I think back (or maybe last as
*maybe* John was implying above with 'last node in a path') would be
the best name for accessing the last component in the path.
