I think you've already provided an explanation for this in an earlier post. Since Jabba was a puppet it wasn't really feasible for him to be pulling Oola around, so Femi had to do all the action herself pretending to have a violent tug of war with the hutt. So it looks like she's the one yanking on the chain while Jabba is just sitting there more likely out of inability to do it any differently. If it was done intentionally it was to show how horrible his plans for her were and just how frightened and digusted she was. My bets are on the first explanation though.
