Absolutely correct All that decal reads or states is that it complied with all of the Federal Motor Vehicle Safety Standards (FMVSS) during the month that it was deemed finished by the manufacture. If for instance it was a '69 model year (which didn't have a date or a VIN on the sticker/decal) that was finished or finalized in December 1968 and it didn't have head restraints (aka head "rests", which were mandatory as of January 1, 1969) and an owner or passenger suffered whiplash then the manufacture was not liable. Just a compliance label like the tire pressure label also in the door jam/frame. Later was the GVWR and emission compliance labels, unleaded fuel only, seat belt labels, and even "Objects Are Closer Than They Appear" If it were really more than just a compliance label they would have made it tamper resistant and not put it on something you could just easily unbolt or remove and move to another vehicle.
