(This is what I'm going to use from this point on, makes my job a lot easier! :-P )
i.e. it's a special case of the Conway polynomial satisfying a special parametrization.
In fact, this holds if we substitute by any power series that starts with (e.g. , ).
I think a more accurate wording would be ' of any chord diagram of the diagram with a chord replaced with a bridge of the diagram with the same chord removed'.
with a splitting on the left given by the writhe.
