You're confusing the path, which is a name, with the
object that it names. It's called a path because it's
the route that you follow from the root to reach the
node being named. To reach a subnode of N requires
following a *longer* path than you did to reach N.
There's no sense in which the *path* to the subnode
is "contained" within the path to N -- rather it's
the other way around.
