Any population of animals will expand to match the food supply.
I think that's the idea of TNR; the existing animals--who now can't breed--will eat the food supply of potential pregnant females and kittens, so the in-place population doesn't increase. I don't think the idea is that the TNR-ed animals will fight off strays from outside the colony. Once any animal is removed from the group, through adoption, euthanasia, or some other kind of death, the food it would have eaten is now available to support one new animal, either incomer or kitten.
But if you don't change the food supply, the population remains the same, one way or another.
