You're Correct!

A walk through golf swing refers to a drill that can be used to help you learn how to transfer and move your weight more effectively on your down swing and through impact.

This is a very effective and useful drill to work on if you struggle to transfer your weight on to your front foot through impact and into your follow through. If you find that you have more weight on your back foot as you strike the golf ball and that you do get your back foot up off the ground showing the sole away from the target on your follow through, then this is the drill for you.

Playing through impact with more weight on your back foot, your right foot for right handed players, causes a variety of swing issues for golfers. Initially, having too much weight on your back foot means that your centre of gravity is too far behind the golf ball, or on the right of the ball as you address it. The bottom of your swing arc, or the lowest point for the club head as you swing, should be at the golf ball or just after it. The bottom of your swing arc is opposite your centre of gravity.

With your centre of gravity back behind the ball, the bottom of your swing arc is before the ball. The result of this is that the club head will strike the ground before it strikes the golf ball and you will hit a fat golf shot that falls short of the target. If you do not catch the ground with the bottom of your swing arc then you will swing up at the golf ball and connect with the upper part of the ball, now hitting a thin shot, a low short shot. A good, solid connection between the club head and the golf ball becomes difficult to achieve if you do not transfer your weight correctly on your down swing and through impact.

A further issue with having too much weight on your back foot is that your body will not rotate towards the target through impact and your arms will take over and rotate more than they should. This will close the club face and also force the club head to swing on the inside of the target line rather than extend down it and this will give you accuracy issues as you will hit a lot of your shots left of target.
The final issue with your back being too much on your back foot through impact is that you will not hit the ball as far as you could if your weight was moving towards the target as you were swinging the golf club.

To improve this swing characteristic, use the walk through golf swing. This requires you to make your down swing and then take a step towards the target with your back foot as you strike the golf ball. Doing this will encourage you to shift your weight on to your front foot, as without doing this, you will not be able to step through with your back foot.

A walk through golf swing does see the player using it to literally hit the golf ball and then walk after it. However, the purpose of the walk through is not to speed up play on the golf course. It is to assist in weight transfer during the down swing and through impact.

A walk through golf swing helps you to transfer your weight more effectively on your down swing and through impact. It is a drill to use as you are moving the golf club towards the ball and target and has no relevance to your back swing action at all.

A walk through golf swing certainly helps you to get through impact and into your follow through but as you actually walk after the golf ball, it does not help you achieve the correct follow through position, which would see you static and balanced on the spot.
