I just tried a little personal experiment and I can manipulate my arms into all 3 positions well within 0.5 seconds, without exaggerating the movement. Start with your hands clasped (as in the right most image), then put your arms down but starting with your left. It also seems plenty bright enough to capture without motion blur. It could hardly take long to do some basic zonal stitching too. Having a hard time following why the case should seem so definitive. iOS does facial recognition for focusing ... wouldn't surprise me at all if the computational photography took a close-in-time separate still of each person, to get them as in focus as possible. It'd be pretty cool.
