Yes, and, of course, owing to that and similar wording on competitors' products, the panic swings both ways. For some people 801 ppm phosphorus is too much for a gasser and worthy of going elsewhere. Others see emissions system wording on an HDEO label (the wording goes back at least as far as CJ-4) and all of a sudden it's somehow a watered down automotive low SAPS type brew, whereas even a real low SAPS E6 lubricant will have phosphorus at the upper limits, SA at the upper limit, and TBN in excess of anything this side of a legacy HDEO or an A3/B4.
An ordinary HDEO like T6 5w-40 will have no more phosphorus than a robust A3/B4. Of course, some A3/B4 lubes will have less phosphorus than others, and the same applies to HDEOs. Assuming the Mini doesn't actually need something like a C3 (i.e. a diesel DPF), there's no concern.
