Is the illustration of the volume rendering technique correct?

Since the formula is recursive, and the earlier pixels are already accounted for in the B row, we shouldn't have to sum the C row, right? After all, each B already contains the blended contributions of the column before it. So the final pixel is just (Voxel value * Opacity) + (B * [1-Opacity]) = 191.4, using only values from the final column.
