I suspect that there is a difference assumed for an American vs European buyer's likelihood of wanting convenience vs precision respectively.
Otherwise perhaps the suspensions are different
Why have 1 placard for 2 countries? I've seen plenty of placards for differences in weight and speed, but never for different countries (I presume the options for speed were for Germany as the listed speeds were not legal elsewhere).
My sense is that yours is a result of a particular German engineer obsessed with efficiency and therefore overlooked the fact that there was going to be a Canadian BITOG member who would buy an M5, let alone Americans who would get confused.
Suspensions were identical for the car regardless of the target market, so we can strike that one from the list.
My leaning is toward your first point, and that is that Americans are unaccustomed to running different pressures based on how they load a vehicle and subsequently they just came up with a "compromise" that would work regardless of how the vehicle was loaded because it would never see the sustained high speeds that it would in Germany.
