Does he work for BMW, and can he put that in writing? If that was indeed the case, why would not BMW simply disclose it?

I did not see any noticable difference between the car's performance before and after break-in. I did not red line it before 1200 miles, I did go WOT several times. There are many members on this board who drove it hard off the lot. Nobody has reported any significant difference after break-in as far as I know. That said, the car is supposed to get a little faster with miles, but that's simply due to moving parts being broken in.
