MLB playoff probabilities

Can someone explain to me how the Diamondbacks are at 38.5% and the Dodgers are at 80.7% when the Diamondbacks have a better record?
Are they taking into account strength of schedule the rest of the way or something?

If I had to guess without looking it would be because Rockies and dbacks have a series or two against each other still. But that could also make no sense at all
