The movement or posture is called Manji uke in Shotokan. Wadoryu hardly uses these kinds of names for techniques, but in Shotokan they do. Wado simply calls this Morote uke (using both hands) or Jodan and Gedan uke or something like that. They are more regarded as two hands doing something at the same time as opposed to being one form (do not mistake this for one movement).
Anyway, I thought to share this information with you as I am sure that some of you reading this might take interest in this kind of knowledge. The name Manji uke comes from the Kanji which resembles the posture.
Manji is written like this: 卍字.
Of course, the resemblance has to do with the first character, which you most probably recognise. Do not confuse this with the Nazi symbol, which is the other way around and tilted to a 45 degree angle. They might have copied it from this Kanji though, as this symbol is around in Buddhism since before the birth of Christ.
You can execute these movements by either withdrawing the left foot and keeping your arms in place before you move to the next one, or turn your body into the next direction as you withdraw your left foot and bring your arms together (as pictured). Have a look at the video, where I show both ways and explain the benefits of each way.
