The first piece covers the whole of the prepared area, like laying it in a saucer (with a hole in the middle). Each subsequent piece is smaller until you have nearly filled the saucer level. The final piece being the size of the original hole
You stop just short of filling the saucer level in fact to allow for shaping a fairing
By bonding the patch into place in a large-to-small-piece sequence, you will eliminate the possibility of sanding through any of the cloth layers when fairing the surface.

West is just their opinion. You need to read less and get out more. Real World experience generally trumps Goggled answers to questions about subjects that you have no actual experience or understanding of.
