Adjustable pushrod extends because it is made from two pieces and screwed together such that you can adjust the length. This is strictly a measuring tool to establish the pushrod length required for a given setup.
Adjustable rockers are something like the cranes, where the lifter preload can be infinitely adjusted by the adjustment nut. However, as the rocker is adjusted the preload is changes as is the wipe pattern so their setup is a little more involved than something like a Yella Terra, where the fulcrum is fixed when the bolt is tightened up.
On the Cranes the adjustment is made at the fulcrum whereas with Jessel it is done at the pushrod itself since the pushrod cup is on a threaded adjustable piece. If you look closely at the photo, you can see the adjusting nut that holds the rocker to the stud.
