I disagree it's unlikely. All it takes is that the colony ship that brought to the first destination not get dismantled in setting up the colony. Give it a decade or two of space industry, you can replenish all the resources it needs to go on to the next destination. In fact, if it's a
generational ship instead of
sleeper ship, they may even have the necessary population already aboard due to growth. And if it is so, then there's a non-zero chance you have factions aboard that don't want to live on the same planet as those who did settle. Or don't want to live on a planet at all.
This is even assuming the colony expedition is a single ship, something I've argued is unwise (single point of failure). If you had two or three, then one of them might decide that it wants to proceed onwards, after exchanging colonists with the ships that aren't going, and replenishing reserves.
Even if you did dismantle it, assuming they weren't stupid to lose all their space-based industry and know-how, they can easily build another one in a century or less. Earth / Sol must have been sending them in droves, so the cost of the ship itself is not that great. In fact, if we took one of the Anthology short stories as true, reaction-thrust ships were being sent several times a year from Sol.
Or even all of the scenarios combined: none of the ships get dismantled so they all will journey onwards, and the colony did build another trio to sail forth.
Plus, you don't actually need to do a good job at it. With sufficiently many colonies doing this sufficiently many times, averages say there will be some success. We have two examples of colony expeditions that weren't exactly successful:
Calvin's Hope and Grayson. The former was apparently sufficiently-well funded, but not with support of the government, so if the new colony's government did want to support a new ship, they could. On the latter's case, they were so adverse to technology that it's a miracle they even consented to boarding the ship in the first place (they must have all considered that to be their Test).
