After putting in the filling, he folds the edges of the Naan up similar to creating a pizza ball which will trap some air inside to create bubbles.
He then slaps the Naan between his hands to 1) get rid of excess flour and 2) pre-stretch it a little.
Finally he makes sure not go over the edge of the Naan when rolling it out in order to leave some air trapped inside, too.

Is it him pressing the dough with his fingers to create thinner areas that will puff up more creating the bubbly effect on the surface
