You're Correct!
Lets face it, toe strikes are much more appealing than heel or hosel strikes because they affect direction less but they also sacrifice a lot of distance with a horrible and weak feeling through impact.
A common cause of this strike is the extension of the arms through impact and this is caused by an out to in swing path which brings the club and arms closer to the body on the down swing. This swing can cause the heel strikes so it is very important to make sure that this is really the cause.
Concentrating on one aspect of the swing can help other aspects and you should purely focus on your extension. You need to extend your arms and golf club to the right of the target because currently it would appear that they are pulling across your body with little or no extension and pointing left of target.
Pointing the club to the right of the target will encourage an improved swing path angle and a centeredness of strike. This swing path will also promote a draw shape where the ball moves from right to left through the air and with a strong trajectory so be aware to allow for more distance and consistent ball striking!

Specialist chips like the flop shot almost require a full swing so interpreting a putting stroke would not create the necessary club head speed or spin on the ball to get the height in order for the ball to land and stop quick enough, for example, over a bunker or on a downhill slope.
A flop shot requires an open faced club for increased loft, therefore the stance needs to be adjusted so the player can aim correctly at the target. It is then important to swing along the line of the body, cutting across the ball to create as much height and spin as possible. This full swing movement will use the wrists that invariably will increase the angle of attack which creates more spin. It is an extremely high risk shot so must be practised intensely on the practice ground.

Some golfers can chip extremely well with a wristy chipping action, but consistent golfers chip well with a more simplistic and pendulum like action where parts of the putting stroke are incorporated into the swing.
A player who uses a lot of wrists during a chip shot can create an immense amount of spin through club head speed and strike, however, it can and will lead to an array of bad shots such as the thin shot where the wrists work too early on the down swing and the clubs angle into the ball shallows and hits the middle of the ball.

Chipping is not about power and speed. It is about finesse and control, therefore swing speed into the ball is totally irrelevant unless using what we may call a specialist shot, for example, the flop shot or a chip from very thick rough where spin and momentum are required to produce both of these shots.
