Subject: Why is a triangular array needed to store the PV?

I'm curious why a triangular array is needed when storing the PV. What is wrong
with having a regular array that stores the PV? In other words...

move pv[MAX_PLY][MAX_PLY]; // <--- why do we need this?
move pv[MAX_PLY];          // <--- instead of just this?

Since you only use pv[0][0], pv[0][1], pv[0][2], etc. I don't see why you can't
use a one demensional array to store the pv in. There must be some reason
because when I searched the net and the CCC archives everyone explained it using
a triangular array, but I can't seem to figure out why this is necessary. Anyone
know the reasoning here?
