He didn't. If you break down that field you see:

    $2a$
    10$
    Bho2e2ptPnFRJyJKIn5Bie
    hIDiEwhjfMZFVRM9fRCarKXkemA3Pxu
    ScottHelme

2a = bcrypt, 10 = 2^10 rounds, Bho2e2ptPnFRJyJKIn5Bie is the 22 character salt, hIDiEwhjfMZFVRM9fRCarKXkemA3Pxu is the 31 character hash value, and then there's ScottHelme. Best guess is that the archive.org folks just appended the user name to the stored hash. Maybe once upon a time they didn't have a username column in their table and this was a creative way of adding it.
