They are both recognized moves. Veena (and most people I know at least) call them Gemini switches and Scorpio switches. When you break them down, it is just Gemini to inverted thigh hold, continue moving body to opposite side of the pole (so your outside leg hook becomes an inside leg hook without doing any leg switching) and then doing your leg switch into another outside leg hang. There you have it – Gemini to Gemini. For Scorpio switches it is just the opposite. I am still learning these, and for me it was very helpful to begin by breaking the combo down into constituent movements that are already in my vocabulary like this. Then as I get more comfortable with the transitions, I speed it up. You have to be comfortable with leg switches on both sides and in both directions (Gemini to Scorpio and Scorpio to Gemini) in order to do these moves. Hope this helps. Veena has great breakdowns on both of these combos in her advanced lessons section.
