Edit: Sorry I wanted to add, don't get hung up on the study, and don't spend more than 3 minutes on it. The idea is to give yourself a larger work space, without having to do a complete drawing, and you're only working on ironing out the area you originally found hard to understand in the full gesture drawing.
If you found this was helpful, do studies on the other areas, then piece then together in your brain and do a full figure but again only 3 minutes. Because what you're trying to develop is the thought process you did to do both exercises as one exercise. What is a full figure but a series of connected studies, others simply work faster, more simpler than we do... I hope that helps.
