How to understand portfolios?

I'm trying to generate a mnemonic code and everything that goes with it. I'm using c ++ / libbitcoin, using the following code – https://github.com/libbitcoin/libbitcoin-system/wiki/Examples-from-Addresses-and-HD-Wallets

When I compile and execute the following code – get this output

Address, WIF, Wallets:

When I take this generated mnemonic and put it on this site – https://iancoleman.io/bip39/

I receive completely different paymeny addresses.

While digging into the source code of libbitcoin, it contains very little documentation about the functions and this is the only code example I found. So can any one help me generate a portfolio in libbitcoin where the data is recognized by other portfolios / services? Thank you.
