OB. Here are some drawings to help clarify. But just understand that fanning and extensor lift up are simultaneous. The deltoid muscles perform both motions. The combined motion is like that of a bent over deltoid fly with a bent right arm moving up, away and back simultaneously.
NOTE: That the on-plane right forearm and the Top of swing right forearm have the same bend except that the top of swing forearm has an additional one inch bend for cocking the left wrist. Hackers will have a very bent right arm at the top of the swing. The first bend (95% of total combined bend), which establishes the swing plane is determined at impact fix.
