Well, that is one way of fixing the problem. You flattened your swing plane a bit and more importantly probably didn't come inside quite as fast and far because of your outstretched arms and larger arc. I guess if you get stretched out really far, there is no way to come over the top. I guess it could cause other problems though. To answer your main question though I think setup with the driver is very important and has elements too it that are different than setup for your other clubs.
