Not sure I understand the questions... but SHOTS/ISOMOTION and ISOMOTION/SHOTS are 2k13 settings. The first is your primary Control Stick action, the 2nd is the one you get when you hold L2 (LT).
The Pro Stick puts both Isomotion and Shots on the RS with no modifiers. Tap for Moves, Hold for shots. This is the default config in the shipped game. When you hold L2 (LT) the Right Stick is used for flashy passing.
