I never really paid attention to this shot before, but I think it is a good one to learn. If you have a potential break ball (the 2 ball), but you need to push it up higher, this is a great shot.
What makes it a "reference" shot is that you can play position to get straight in on the 1 ball, and cheat the pocket to create the two rail position play. Of course, the rebound direction will vary with the starting cb/ob line up, but once you get a feel for that, this becomes a pretty forgiving and consistent shot. There should be ample opportunities to use this shot since there are typically so many balls in that area.
Of course you won't be successful all the time, but it can be one of those shots you try while on your way to clearing away balls.
