I have tracked ex-military people who knew they were being followed that did not even think of concealing their prints. I would say the probability of an abductor attempting to create a false print field to be too low to calculate. That person would need to be a forensic expert.
As I noted, the print was deeper at the toe than at the heal with mounding on the sides meaning that Jacob was leaning forward, but not pushing off hard. Other than getting into the back of a vehicle, what other reason would he have for leaning forward? You are getting into a vehicle like an adult where you turn and sit down. My kids dove in and this would be even more applicable if he was told to lay down on the back seat, or if there was an associate grabbing his arm and pulling Jacob in.
