3 man mechanics - the triangle?

I have heard that the principle is that on a drive to basket the 3 man (triangle) pushes up to the baseline, ie L and C squeeze up.

Could you explain this more? I know that on a drive, the lead closes down (i.e., moves to the elbow) and on any shot attempt, the C and T take a step or two down toward the baseline to see rebounding better. If this is what you're referring to, I think it's been around for quite some time.
