As mentioned before for the endo to mixed grip full pirouette combination, some of the gymnasts' main goals are to clear the rail, to flow from the endo to the pirouette without a large pause, and to swing down square. Notice how the gymnast keeps his eyes on the bar during the full pirouette.
The gymnast then makes a backwards roll to dislocate. The athlete must shift the wrists to maintain proper weight support at peak height or his body may collapse against the bar. Notice also the wrists shift on each inverted giants ascending phase to support.
