Yep. It's so when you move it in DEC the counter weights don't turn as well. It eliminates the potential out of balance issues sometimes encountered if for example the weight/DEC shaft is slightly bent or the counter weights are slightly off centre in relation to the shaft. Brilliant yet simple. My compliments to the craftsman that designed & built it.
