no, that first one is perfect, any closer to the node than that and you risk damaging it.
I thought that about the second one, but apparently it's better to go close to the node and have a smaller cutting than cut in the internode.
Once the xylem's been removed in a complete ring like that (in trees it's called 'ring barking') the water has no way of getting up from the roots.
The plant is doomed.
