It's not intended to do that. It's directed to a particular...say somebody had a wife who had some connection with some company. The screen would say that nothing relating to that company can come to you for a decision, but if something for some other company that nobody ever thought of that had some connection with you comes to you, then you'd recuse. Then I'd look at it and say that you had better put a screen up, and so they'd put a screen up for that one, too.
The screens are directed toward particular problems. They're not something that avoids all recusals, if I can make myself clear. People seem to have trouble with this.
