Your ignoring physics here, you don't magically get twice the strength using two swords over one sword with two hands then your damage is the same because force = mass * accelleration and there is only so much force you can put into your swing so twice the mass means half the accelleration, the resultant force is again the same.
In reality you slightly more as you increase mass but I doubt two half weight swords would be as easy to swing as one normal weight sword (or two normal weight to one double weight, whichever you perfer).
As to larger surface area, pressure is force over area and we know the force is the same, or there abouts, so as you increase the area you decrease the power. This is why stiletto heels on a lithe girl will damage floors but the fat guy in sneakers has no effect. There is an argument that assuming you sill have cutting power to penetrate armour, clothes and skin then you'll do more damage because the single edge has an excess of force behind it and a lot of wasted. Although I would imagine this would have involved cutting clean through the body and so probably a mute point.
I won't disagree about a two weapons style being a good thing in general but the line of your argument is just wrong.
