Well, PG presents them as different bets, one of which paid off. They were the same essential bet from Newton's perspective. For example, books on physics at the time referred to religion heavily, sometimes as a cornerstone of an argument. Even Newton's Philosophiae Naturalis Principia Mathematica says "Collocavit igitur Deus Planetas in diversas distantiis à Sole, ut quilibet pro gradu densitatis calore Solis majore vel minore fruatur."
