I don't know who these folks are and how well their info stands up to scrutiny. For the time being lets assume that what they say is true and that there is no noticeable effect unless you sterilize 70% of the population. If you believe that it is better to leave the TNR cats out there because there are other non-TNR cats waiting in the wings, then you could sterilize 100% of the cats coming to your feeding site and it would not be enough to make a noticeable difference, again, because of all the non-TNR colony cats that are supposedly being kept at bay by the TNR colony cats. Plus, in reality you are never gonna catch 100% of the colony cats so the odds are even worse.
Some interesting points that they make. Use limited resources to achieve the needed 70% in small areas. This means make no effort in other areas. I say this is the same as trapping cats in your area and dumping them elsewhere. The demographics will be indistinguishable.
