Xi and Putin's new world order dance routine

What's with the weird pose by Chinese President Xi and Russian President Putin at a photo op at the BRICS summit at Kazan recently?

As Putin outlined his "vision of a new democratic world order" [sic] to the expander BRICS delegates, this photo really stands out to me. Was it just coincidence that they were both digging in their jacket pockets at the same time? Was it part of a dance routine? A nod to Napoleon Bonaparte? Is it maybe some new kind of salute? Will we all have do this in the new world order? I'd like to know.
