The forward press thing was his tip to amateurs that are too "static" at start up. I also think it's his way of getting to impact fix.
Stadler can still move it out there and I see he leads the Champions Tour for driving distance at 292. I have to believe he uses 4 barrels, thus his comment about pulling and his pivot. Although I sensed more pivoting and pulling in the slow-mo sequences they showed of him than I expected to see, the thrusting of his right arm was very clear and heavy!
