It's my opinion that such twists, swipes etc are symptoms, not causes of bad shots. They're caused by poor bridge placement and the subconscious movements they lead to during delivery.
I've done some testing with a fixed bridge and found that if the bridge doesn't move, and the bridge is near to the effective pivot point, then almost all jabbing, swiping, wrist twisting makes very little difference to the shot, providing you don't swerve the shot a lot (by soft hitting with elevation) or unless you impart considerable outside english on the shot.. say more than 1/4 tip.
Swiping itself, if you hit near CB center does very little to change the line of the shot as determined by the bridge position.
I believe most people can move the cue pretty straight... try the in and out of a beer bottle drill. It's the 2nd guessing of the line of a pot that makes people cue weirdly.
A good remedy is aligning, locking bridge, looking at only CB during the stroke and hit it with a straight stroke in the center. You'll soon discover the inadequacy of your pre-alignment. This helps one to develop better pre-alignment.
