It is a handy tip. A tucked pinky changes the balance of the ball in your hand. It is lifted up slightly, consequently you give a bit more finger action and side roll on the ball, due to a stronger leverage position. It may not be much, but it creates more power, revs and hook upon your normal release, which results in a 2-4 board adjustment on the approach? Additionally, the ball will come easier off your hand since it sits more loosely in your palm and gets better support by your index finger, which also gives more side roll.
I use this technique, too, and it works. Especially on oily conditions, when I need some extra punch or when I get tired and need some "other" muscle tension. I do not like to keep it up all the time, just some frames, because it squeezes my pinky and aches.
