Sure, this is one scenario. It depends. It isn’t always one way.When your opponent catches your kicking leg, if you pull your leg back, it won't work. If you drop all your weight on your leading leg and step down (follow with a hammer fist on top of his head), your opponent may not be able to hold on your entire body weight.
So to step down after kicking instead of to pull your kicking leg back is a training to counter a leg catching.
In CMA, a kick is a step, a step is a kick.
