How is it that you can refreeze some foods that have been previously frozen and defrosted (by a supermarket) but you cannot refreeze defrosted items at home?

Question

Today I bought some food that I had planned to freeze for use on another day. On the back of the packet it detailed that it had previously been frozen but thawed under controlled conditions and that it was safe to refreeze. I had always thought you couldn’t refreeze once thawed. How can supermarkets do this differently to me at home?

If at all contextual, I live in the U.K. and it was a curry.

Most frozen food at the store has been flash frozen. Making it safer, higher quality, and longer lasting. You don’t have this ability at home.

The package said “controlled conditions,” you also do not have this ability at home. This gives your food a higher chance of growing something dangerous to you. Most likely, it will just ruin the quality of the food, not make it dangerous

It is likely not the supermarket, but the manufacturer. The supermarket just stores the food created somewhere else
