Great question — answering as the UphillTech team:
This is actually the recommendation of a lot of mass produced items. They might have been contaminated after being made, and the producer wants to ensure that you kill anything that might have been introduced. A cynic would also point out that this shifts liability to the consumer, as if you get sick from it, they can insist that you didn’t follow their reheating instructions.
