Any case, this is great variation. and may be attempted from the side-crow by splitting the legs when up mid-air. The other version, which I also tried long ago, takes the opposite leg in a similar split. More difficult. Getting back to this pose... soon, my entire batch should be doing it!!
Now, the most interesting thing about all this learning, is that just today I learnt another way of entering the pose, without moving from the side-crow. It is sooo easy, that I can teach it far faster to my students, who will learn it sooner than I did (I took an eternity, and am still struggling:)
(Tomorrow, some more stuff on that sage Koundinya)...
