Watch as Coach explains, and high jumpers demonstrate this short approach box-assisted drill. The box allows the jumper to focus on action/reaction and the timing at the bar as it pushes the jumper higher than normal. The jumper wants to land on the box's sweet spot to initialize the action/reaction aspect.
