They believe every american at birth is given a secret bank account tied to their social security number worth millions of dollars and this is how you "authorize" someone to draw funds from that account. It gets even better when you ask why would the government create secret bank accounts for people: it's because the government sells babies to cover its debts since they ran out of gold.
I usually need to be way more stoned to connect the dots but I'll give it a shot. They are a living breathing flesh and blood person. The money is in an account for the estate "of the same name". One of them is the ALL CAPS name and the other is the First Letter Caps name. The person for some reason can't access the account, but other corporations are allowed because... yeah I need way more drugs to finish that. But that's roughly the idea... I think?
