Since you are apparently a young'n, I'd recommend to watch this with an adult. I think Kelly doesn't use any provocative language but it might be best (He does have an uncanny way of talking "CrossFit Hip Jargon" but he I want to say it's WFS because he has his kids on the videos at times.) For some mobility tests, it's hard to do them yourself.
Really what it gets done to is searching for what muscles are too darned tight and stretching them. This can be a bit of self exploration. Oh, that muscle is way tighter on my left than my right.
But the fact that it's one hip, makes me think something is way too tight on one side. Happens pretty easy when it comes to dominant side sports such as your switch leap and vault and tumbling (my right hip is notorious for this unless I work on it as I had to during my tumbling and vault work).
