If you can get the vid to work, start at 41 minutes. Looks like Roman style is what we usually see from the popes. It's not a handshake. It's approaching the other, clasping the upper arms or shoulders, and pressing cheek to cheek. Doesn't look any different from other masses I've seen celebrated by recent popes.
Thanks! And no invitation to the folks to say “Howdy!” to one another? ;-)
