Exactly .And in MX/SX it's usually a step-on/step-off.
Depends on exactly how the feature is set up. If there is a big elevation difference between the lip of the first jump, and what you're landing off, then that's the step-up part. then if what you're jumping off has a landing much lower, then it's a step down. So step-up to step-down, or if it's all relatively the same height, step-on/step off.
