Whatever it takes!!!
I think his point was that Waqar didn't have a conventional inswinger and with the old ball only really had the reverse inswinger (ie) both with the new and old ball, he generally got it to move only one way... Out with the new ball, in with the old.
Only a rare few like Wasim and Anderson can get it to consistently go both ways with both conventional and reverse swing.
You don't need a conventional inswinger to take stacks and stacks of wickets with swing bowling though. See Steyn, Dale
Yeah, to determine whether someone is a swing bowler you ask whether they use swing as their primary method of getting wickets, not can they bowl inswing/outswing/backswing/squareswing/slantswing and so on. Steyn only swings the ball out but he has possibly the best out-swinger of any bowler ever, and picks up lots of wickets with it. And I don't think there's any swing bowler who's been really successful who hasn't also taken wickets using movement off the pitch, as that's simply what happens.
None of you are wrong, FWIW. And OS, there are loads of bowlers who get the ball to move both ways at will. They were just not very good bowlers either due to lack of pace or direction or discipline or any combination of above factors. Case in point - Debasish Mohanty.Fk all of you, I only consider someone a swing bowler if they can do both the in and out swinger
