You don’t technically get any “more” points for extra Attacker Kills.
Whether they indeed did have to do an actual fight there (duplicate defender), or not, they would get (at best, assuming the fight was a single-kill fight) a full 80x3=240 Attack Bonus, whether there was a defender on the node or they are just traveling past an empty numbered node.
At worst, it would have maybe only affected your opponent negatively, if indeed they did have to fight a duplicate defender there, and happened to have needed 2 or more fights in order to defeat that node. Then they would have lost Attack Bonus
But it would not have caused your own team to have lost ground to an opposing team who somehow had more that 150 Attacker Kills.

It seems there was a placement bug where a defender was moved, but remained on the first node as well.
