65% (59,253) of children whose parents do not have a high school degree live in poor families.
42% (72,939) of children whose parents have a high school degree, but no college education live in poor families. [1]
There are a number of factors that contribute to child poverty and upward mobility, but it may be a bit hasty to suggest that the primary hindrance to upward mobility is single parenting per se. The study states that they are strong predictors, but that does not preclude other factors that may be correlated with single parenting.
This is hinted in the final sentence of your quote. If children of married parents have lower rates of mobility in communities with more single parents, this would suggest that the effect may be not the sole result of the parental structure, and instead associated factors such as socioeconomic status, social norms, education, etc.
