There is a flat nylon strap that "weaves" through the inside of the stages. The strap causes the stages to cascade. The strap is similar to what you would find on a backpack. When you extend the 1st stage then next one extends as well. I believe you can see the mounting brackets and roller assemblies for this strap in the CAD if you look closely at the ends of the stages.
The 2011 arm is pneumatically extended. There are two pistons, back-to-back, attached to only the 1st stage. The nylon strap then cascades the rest of the arm. The back-to-back pistons allowed for 3 different extended positions.
