Footnote error in lab2?

[ifsheldon]

This line says, "Note that the last qubit is not actually connected to the first one, ...."

https://github.com/qiskit-community/qgss-2025/blob/237853c994b30b45ff83cf94631f548f8fed1ad7/lab-2/Lab2.ipynb#L347C84-L347C91

I think the code corresponding to this footnote is

qgss-2025/lab-2/Lab2.ipynb

Line 366 in 237853c

"graph.add_edges_from([(edge[0], edge[1], weights) for edge in generic_backend.coupling_map][:-1])\n",

However, when I print the edges added to the graph, the result does not match the intention of the footnote.

# the result of [(edge[0], edge[1], weights) for edge in generic_backend.coupling_map][:-1]
[(0, 1, 1),
 (1, 0, 1),

In the code, there's one edge from Node 3 to Node 4 but no one edge from Node 4 to Node 3 while the last qubit (Node 4) is connected to the first one (Node 0) since there're 2 edges connecting them. So, I guess the footnote is wrong.
