i have seen people using this drill but

1- what does the drill teach

2-how or what to do it correctly?

Since reading TGM, I would say that the drill teaches:

.3)How LAG is generated by the Pivot
.4)How LAG is effectively felt by the # 3 PP
1) The position of the hands and arms in catching LAG pressure against the # 3 PP
2) The quickness of the Pivot in sustaining the LAG
3) How to direct the LAG through the Plane

I'm sure there are other things.
