Many times we see in kitchen when someone makes Roti, they first take the atta (flour) and make a circle shape (not perfect but ideal case let it be) we often see when the roller is moved above it to make the roti more flatter and circular, the roti rotates by itself to make the portion which is not yet flattened more to get the chance of flattening, how does this happens?

A video demonstrating the process: https://youtu.be/BPeY0XloQ0Y?t=76.
Update: The method seems to be rolling forward and backward through hands and at some critical times the Roti starts rotating a bit . Maybe somehow some force is providing a torque about centre , could the reason be friction?
