Let me take the liberty to explain before Raff does. Delta of points mean difference between two position. Let's say that you have a point in a mesh at [x1, y1, z1] position. And then for the same mesh you apply some changes through deformers / ops as a result this point now moves to a new position [x2, y2, z2]. Then a Delta of Positions between these two positions of the mesh will be - [x2-x1, y2-y1, z2-z1]. The Delta Positions would be an array of such difference positions of all the points in the mesh. That's mathematical definition. In simpler terms, it is just the information which records the difference in the position of each vertex in a mesh between two different states.
