it's a scenario that we have discussed many times here
- ball goes into touch outside the 22m, but rolls past the (imaginary, extended) 22m line, and defenders take the QTI from behind the 22m and kick to touch -- was it carried back in to the 22m? or do they get gain in ground...
We now have an answer. From next season in SA the defenders would get gain in ground. Which implies that, currently, it would be counted as carried back.

6. Quick throw-in
a. The ball is kicked by an attacking team and the ball rolls into touch outside the defending team's 22 and keeps on rolling. If it then rolls beyond the imaginary extension of the defending teams' 22-metre line and a defender picks up and throws in quickly to a team-mate who kicks directly into touch outside of his 22, the line-out will be where the ball went out.
b. The ball is kicked by an attacking team and the ball rolls into touch outside the defending team's 22 and a defender picks up, runs back behind the imaginary extension of the 22-metre line and throws in quickly to a team-mate who kicks directly into touch outside of his 22, the line-out will be opposite the place where the kick was made.
