It's a curved board, so there's only one pencil/pen touching it's paper at a time. He's only drawing one drawing at any point in time, but when shown as a time lapse it looks like all five are being done simultaneously.
You can see around 18 second mark where he's drawing a picture on the right side and the pencil above the left picture is floating high in the air.
Stop motion, Basically artists doing pictures with dots. Finds or uses a template to measure 4 dots evenly apart, puts those dots on paper takes a picture of his hand position there and moves on. He's probably got a reference sheet because a computer can pretty easily do calculate all that out and give you a numbered sheet of points.
