• The original statement Dror made here was '$W_{j_{n}}$ of any chord diagram is, you EITHER replace a chord with a bridge OR you replace it with $-2$ times a nothing'

I think a more accurate wording would be '$W_{j_{n}}$ of any chord diagram $=W_{j_{n}}$ of the diagram with a chord replaced with a bridge $-2\times W_{j_{n}}$ of the diagram with the same chord removed'.
