I don't know maybe it had nothing to do with where the washers were pressing and I just got a better feel of it by the time I was pressing at the inner lips.
I see the principle behind it. Having the smaller washer inside the cup basically centers the bolt and prevents lateral movement of the tool while tightening the nut. Now this makes sense. That is one reason I why chose the thickest bolt I can find to minimize this movement. But I think I will experiment with bronze or copper bushing for my next install. Thanks.
