On Gasoline Engines Piston Ring Instructions that come in the Box seem to be made to cover every possible Piston Ring that that particular Manufacturer makes and it is up to the Mechanic to pick out which on of the Instructions matches the Piston Rings that He got.

And, there is always a possibility that something got boxed wrong. That happens less often at the Manufacturer and most often after the Seller gets them.
