Except that’s not the worst case. If the machine predicted you would pick A&B, then B contains nothing, so if you then only picked B (i.e. the machine’s prediction was wrong), then you get zero. THAT’S the worst case. The question doesn’t assume the machine’s predictions are correct.

Good point. Actually I was assuming that the machine’s predictions were never wrong. That’s also what is defined in the Newcomb’s Paradox wiki page.
If that‘s not a 100% given, you are definitely right.
