C3 5W-30 are some pretty stout oils so I'd say they were wanting the comparison against one of the tougher standards to meet?
They should have compared the 0w-16 to the 0w-40 A3/B4 you mentioned, then, particularly in trying to compare TBN.
I won't say this 0w-16 is garbage or doesn't have good anti-wear. There is a reason, however, that a C3 was chosen as an example with which to compare TBN.

They're certainly working hard to be considered a top product.
