You have undirected graph, because:

  6 -> 1 -> 2 -> 3 

You wrote everything correctly, because vertices 1 and 2 have already been investigated, we are completing our study. If the graph were oriented, then it is quite possible that we could continue the path further until we could go around all the vertices. Eh, thanks to Makunin
