Misconception or truth?

I stumbled upon this interesting article regarding polyester strings while reading Most research I've read shows the ball is on the strings for only about five milliseconds. A traditional theory was that string texture could somehow help produce spin by "gripping" the ball, but your study says less friction helps impart spin. Why?

Rod Cross: Less friction between strings allows the main strings to move sideways. As the ball is about to leave the strings, the main strings snap back and give the ball a sideways kick, thereby increasing the rate at which the ball spins as it comes off the strings.
So, textured strings is designed to reduce friction between strings and not to increase 'bite' on the ball? What's your take?
