The ball cuts back in due to the seam gripping on the surface. Same but different.It's not an off cutter. It's the wobbly seam delivery that Asif perfected.
not sure how much basis in fact this has tbhHis 10/77 at Leeds in 1987 is another good example. Most of the movement (on the fuller deliveries at least) is through the air.
Also, the Asif delivery at the start of this thread is as good an example of a proper off cutter as you'll ever see. If you see the replay you see that the seam is tumbling through the air and gripping on the surface. The way the ball is released with the fingers going more down the leg side of the ball means that when the seam grips on the surface it pulls the ball back in towards the stumps. You won't see such movement from a delivery that actually 'seams', as in lands with the seam straight upright, except on very green pitches.
Generally I'd say that the mechanics of the release will largely dictate the movement. A leg side release will cut in, an offside one out. I've heard a rule that out swing bowlers tend to cut the ball in, and in swing bowlers out. If the seam is upright it could move either way though, and if it's wobbly it could grip or skid. Having great wrists helps, and boy did Asif have those. Such a waste of talent, but things like that happen.not sure how much basis in fact this has tbh
sometimes seam is wobbly, sometimes straight, in either case sometimes it hits the pitch and jags either way.
This is the theory, and everyone always says it when you're a kid and you're supposed to be learning to bowl but in my experience it's pretty much all bull****, the ball will hit the pitch and randomly do whatever depending on where the seam hits.Generally I'd say that the mechanics of the release will largely dictate the movement.

Edit: of course the pitch is a factor as well.
