No, the distinction was that the fact that they used RoundUp (which would have killed the crops they claimed to have planted) suggests a motive. The farmers claimed that the seeds had just drifted into their field by chance, Monsanto claimed they'd deliberately planted them. The fact that they sprayed the resulting crop with a herbicide that would have killed their own crop seriously calls the farmer's account into question. How would they possibly have known that enough seed had just blown over the road that it was safe to spray?
