The sourceMethods() method does not give the set of methods that may be
called, but as its javadoc says:
    /** Returns an iterator over all methods that are the sources of at least
     * one edge. */
That is, it returns the set of all methods that have at least one
outgoing call edge. In your example, the foo method has no call sites,
so it is not in this set.

It sounds like you're looking for the set of all methods reachable
through the call graph, which you can get by calling
Scene.v().getReachableMethods().listener(). This returns a QueueReader
which implements Iterator.

Hope that helps...
