He is shifting the loss to the broker. You think he will reload his account if he goes 200K in losses?If he is seeking high leverage, normally it means he is going for super high risks / high rewards.
Then it makes total sense to limit the possible capital loss, by managing the account "reloading/withdrawing".
If I was his broker I would tell him OK, but you put the 90K in a blocked account at a decent bank, and you can only withdraw this money when I agree. If you lose I can immediatelly take these losses from the bank account based on a statement. And he should sign that he will not oppose to this withdrawal in any way. Afterwards he can go to court to (try to) recover his money. I am a broker not a banker. Broker, not broke.
