It is true that the bacteria might have a substantial die back because of the things they described. But, they are the right type of bacteria, and even if 90% died off, you'd still have a nice size colony to get your cycling going faster. Every little bit helps, especially when you are talking about exponential growth. The bacteria can double every 24 hours under optimum conditions. So, ultimately, even a little more bacteria in your filter can make a big difference in the long run. It can cut weeks off your cycling process, and if the mature media contains sufficient numbers that don't die back due to the factors already mentioned, you could be instantly cycled.
It isn't surprising that P@H don't do this sort of thing. They'd rather give bad advice and sell you instant cycling products that don't actually work nearly as well.
