It’s an identifier collision, they’re supposed to be unique. That’s what did SHA-1 in.

SHA-1 is a hash function. What did it in is that there was found a way to make different strings hash to the same value. This is just someone accidentally re-using serial numbers, it's not a weakness in some algorithm.
