If the car is running good when you remove the old belt, why would they even suggest you loosen the cam gears???? Once the crank is at TDC, the belt is removed and the timing bar is slipped into the cams, everything is as good as it's going to get, right? So at that point you just index the cam gears to each other with a Sharpie and a straight edge, remove the timing bar and tension the new belt on. As long as the cam gear marks stay dead on, it's all good, right? What am I missing?
Here's my 2 cents. I think Fords process plays it safe and covers the cars that get out of tolerance. When I did the belt I had two mechanic friends with me, one which was the previous owner. We indexed the cam gears with a marker but when the timing bar was slipped on the marks were off... so if we didn't loosen the gears there was a trade off, either the crank would be off TDC or the timing bar wouldn't slip on. I think that was my understanding of it, it's been so long since I did it. Anyway after the belt was done the car ran great and had more power than I had ever known.
