That's an excellent explanation.

A small correction: if I recall correctly, the Corporation is legally allowed to give some money to the Foundation, and it does so. But the allowed amount is quite small -- maybe a couple a million a year? I don't remember exactly -- and only a tiny fraction of the Corporation's profits.

Yeah, I simplified there. I remembered it being a really insignificant amount that they're limited to, and then more importantly, it's still a non-profit. If they take the money, they're just as well forced to reinvest it into their mission statement.
