Discrepancy in RC/PE4 exercise & technique videos

I was reviewing the technique for RC/PE4 today and noted that there is a substantial difference between the body positions in the exercise vs. technique videos. Specifically, in the exercise video the feet are set lower than the rings so that the body is closer to horizontal while the arms are fully extended; whereas, in the technique video the feet are at a similar elevation to rings making the body decline at arm extension. I imagine there's benefit to both but the muscles recruited are different. Which variation is more suitable to the goal of this exercise?

Hi Dustyevsky, as areference use the previous exercise since it is an evolution, feet should be approximately at rings height.
