The difference is that Jasmine is higher than Kim that she is was on. Jasmine was on 24 ft. while Kim was on 19 ft.
By the way, I think there's a typo here, in Kim's statement that he jumped from 14 ft. above sea level to 5 ft. "above sea level?" Is it supposed to be below? and also, I don't know what's the "Dora cue" about.
