Two separate emails confirming what I thought:
North American Release
International Superstar Soccer-Konami released in North America June 1995
International Superstar Soccer Deluxe-Konami released in North America November 1995.
Anything on the box as listed for SALE in USA, Canada, and Latin America only is considered a North American release, as apparently it is one entity. Similar to how European releases are grouped together for systems over there at least to "us" here in the United States. Apparently ISS and ISS Deluxe exist in this form both with ESRB ratings, so there is your answer, and to why it also contains USA part numbers and info like other releases such as ISS2000 and Mr. Pants.
