• The original statement Dror made here was '[math]\displaystyle{ W_{j_n} }[/math] of any chord diagram is, you EITHER replace a chord with a bridge OR you replace it with [math]\displaystyle{ -2 }[/math] times a nothing'

I think a more accurate wording would be '[math]\displaystyle{ W_{j_n} }[/math] of any chord diagram [math]\displaystyle{ = W_{j_n} }[/math] of the diagram with a chord replaced with a bridge [math]\displaystyle{ - 2 \times W_{j_n} }[/math] of the diagram with the same chord removed'.
