It's still called the inward pull. "Pull" is a little misleading, because you're generating the pull from your hip and shoulder rotation and the muscles in your back, all the while leaving your arm fairly passive, like the guys mentioned. If you use a towel and go through your motion, it's so obvious how much power is sapped when you get too active with the arm too soon. I guess you could call it the inward guide, but that seems a little too abstract...it still feels like a pull even when your arm is passive.
I wouldn't call the right pec part of the throw a pull, or if I did, I'd probably call it an outward pull. But, it doesn't really feel anything like a pull. I think elbow extension, loft, apex, wrist extension, hit, snap, and follow through are terms that better convey better what's going on during the right pec drill. It's where your arm goes from passive to active, which is maybe what Redisculous is saying.
JR, those Finns may be pulling fast from max reach back, but I bet they aren't doing it with pure arm. I've started reaching/leaning way back and pulling very fast for max D and it's made a huge difference. But I still don't pull with my arm, it's weight shift, larger core muscles, and rotation doing the work. Weight shift is a big key in increasing your D once you've started snapping it, I've always just thought of it as helping nose down.
I'm not sure what you're getting at with the heel pivot discussion...
