Interesting read about OEM equipment vs replacement tires.

This is not limited to BMW either, I know Ford, GM, Probably Fiat, and all the luxury brands do this. Tire compound can be customized to create longer wear, less resistance IE better fuel economy, grip in high temps or low temps, etc.
This is why the tires that come on your vehicle might not be the best performance indicator of how the 'same' replacement tire from NTB or discount tire will perform.
Yes, you are correct. I work for a very large OEM tire manufacturer, and this information is correct. I'm not saying that I necessarily agree with this practice, but it is correct as stated, and it is requested by the automakers.
