What the dish soap does is break the surface tension.
Ever see a spider or a water strider walk on water?
Thats surface tension holding it up. Put a drop of dish soap on that pond where it is and it will sink.
Thats what the flies do and is why they drown. They expect to sit on top, land, and down they go.
Oh and dish soap floats so even if you mix it it will come up to the surface. One drop though so that the smell of the vinegar gets through.
