So to be clear how does he actually make money off this?

No, the best you can do is break even. If a bank mistakenly place $1M in your trading account and you decide to use it to trade. If you make $100k profit trading it, they will take the profit plus the orginal $1M as it wasn'tyour money to trade with. You will not get any tendies. If you lose $100k then you will still owe the broker $1M. Alot of risk for $0 tendies.
