Raul, You are correct about the rules of Omaha but this is a simplified version of the problem. It is not intended to be Omaha-specific but could be used in Omaha with minor modifications.
The left box result of "bestLow" contains the ranks as used after we have lowered the value of an ace (normally 12) to be lower than 2 - represented by 0 - so it becomes _1. This reflects a hack of my original high-hand poker code where ace is usually high but could be low in the singular case of a wheel. The right box is as you surmise but my point there is that there are multiple possible solutions because of the duplicate cards. However, any one of them suffices and there's no point in returning all of them. I hope this makes things clearer.
