Yeah, something weird is going on there. 72 years at birth for the Amish sounds absolutely crazy too. Maybe the Amish one is life expectancy at 5 or 20 and the other at birth.
It's possible that they simply have much lower rates of infant mortality. The linked discussion is from pay-walled researchers, so hard to see where they discuss their methodology.
Low incidence of alcohol use, strong communities with a tradition of midwifery, narrow genetic pool (which would tend to exaggerate any gene pool effects) are all things that could contribute to lower rates of infant mortality.
