Your swing plane should remain constant from when you start your forward swing and on into your follow-through. Many make the mistake of adjusting this plane, albeit inadvertently, as they come forward. Usually they wind up in a steep forward swing. The right arm gets stuck beside the body with nowhere to go or the clubface becomes wide open.
Usually golfers compensate for not having an open clubface by employing manipulations during their steep forward swing. They may push the club outside or flip the hands and wrists at the ball. Commonly they will roll the arms; this makes them feel as if they are squaring the club because they are closing it.
Many instructors actually teach these manipulations to their clients but these are just inferior substitutes for handling the club correctly.
