A way of thinking of this "paradox" that I've found helpful is to see the two-boxer as imagining more outcomes than there actually are. For a payoff matrix of this scenario, the two-boxer would draw four possible outcomes: $0, $1000, $1000000, and $1001000 and would try for $1000 or $1001000. But if Omega is a perfect predictor, than the two that involve it making a mistake ($0 and $1001000) are very unlikely. The one-boxer sees only the two plausible options and goes for $1000000.
