It's not saying that. General trends can never predict the lengths of individual labours. All there is, is an association. Seems on average obese women labour for longer, but there are other papers out there showing stage 2 is similar length, and that obese women pushing put the same out of pressure out as other women. It's just stage 1 that differs.
