The image/idea behind throwing the club 'away' from you does a couple things.
First, it ensures you uncock before you roll.
Second as long as you keep your pivot moving, it lets you 'lay the hammer down' for some serious power.
The critical part is keeping your pivot moving, or you give up lag pressure, and that is where folks can go wrong here, if their pivot still needs work.
IMO it is easier to learn a 'sweep' release first, which really lets you feel the uncock, and roll - and - that the roll is really imparted by the pivot for horizontal hinge in a true swinger's move. It lets you feel the 'throw out' of the 'flywheel' as the club swings.
Once you 'get' that feel you can take your release deeper (have more overlap of accumulators).
This is a drill where hitting balls can be a distraction. Get the feel of the uncock/roll/pivot/throw out with slow full motion 'swings' with a heavy club first.
Very much agree Jim - over roll can be a problem - but, the key is really look, look, look and make sure that the clubface is 'on plane' with the toe pointing to the target at halfway back. The real problem with over roll is usually that when people do it, they get off plane. Make sure the butt of the club is pointing at your plane line and your right hand is still in front of your right bicep (don't let it get 'behind' you).
