It really is. I happened to stay for a week in the house of the man who owned the company that (at that time) provided all of the cheese for McDonalds in all of Europe, except Russia. His plants were subject to lots of random inspections where they would not only taste-test the cheese, but chemically and mechanically examine it to ensure that it was the same as was being produced in the rest of the world. I think that the confusion might be that McDonalds has a lot of "local" menu items that you can only find in those countries (e.g.: beer in Germany, wine in France). Those items are very different, but the "core" items, like the Bic Mac in question, are very much the same across the world. I should note that there are a few cheats to this. For example what is called the Quarter Pounder in the U.S. is slightly tweaked in Europe, and I think that is usually called something like "Hamburger Royale", so there is that. But that could go either way depending on how you see it.
