I don't think so. I think it's aimed at a growing "market" here. Spanish labelling in Europe would only be useful in Spain. Products exported to South America have their own labelling specific to the market there, wouldn't be bilingual.
Hmmm Good point.
I did a quick search and found a bunch of US products with bilingual labeling like this one

but you make a good point that it would not need to be for export.
