I believe their point was more that if the whole push was just to inform users that other browser options exist, but they are still running on the same underlying engine no matter the "skin" the browser is using on top of Webkit, it would be similar to forcing Ford to offer alternate colors on the same vehicle in the EU and congratulating themselves on "regulation done well". As someone else pointed out, the legislation does force Apple to allow alternate browser engines, but creating one would be quite a burden for someone like Firefox.
