I dont see a whole lot reasoning over there just a bunch of mumbo jumbo. Your trichomes are the only indication factor that your plant is hitting the right ripeness, Hairs will continually grow, and so will buds, some people may try and get more weight by waiting, saying there buds are small or not filled out yet, but the plant can very well be ripe and should be harvested. There is no good info in that page, i have had new pistils sprout up the week of harvest, but i wasnt going to wait for them to brown out, cause my trich's were already going amber. If you have insufficient lighting or growth is slow, u cant determine ripeness from the color of pistils or from the size of buds. Browning Pistils just means the plant is in the ripening stage, not necessarily ripe. Bud size will be completely dependent on growing conditions.
When your trichomes have hit the cloudy color, all those things he claims u should wait for, should have already happened or are happening.
