One copy might go in their personal safe at home, and another copy goes into a safe located elsewhere, like a climate-controlled storage facility.

It is worth noting that the hash function gives the checksum in the hexadecimal format, which must be converted into binary for a seed phrase to be javascript function generated. For this to happen, the checksum result is segmented into 11-bit lumps of data that map words from the BIP39 word list.
