Well, my logic was that if they knew about the Alliance's plan, they might have built a few to outrace them in their own game: colonize Sirius before the Alliance could.
But, nearing the end of the war, the coalition put these ships aside - as they certainly are still useful, colonizing Sirius after the war would be a fine idea nonetheless.
Where it is hard to explain, is the nomad destroying Earth. For a sleeper ship of the coalition to survive, it would have needed to:
-either be on the right side of Pluto. Which isn't likely, considering Pluto was an Alliance outpost.
-Behind the orbit of a planet, fully ready to enter hyperspace in a few seconds
The second one seems realistical enough - and would explain for instance, how only one managed to escape. But it would probably mean the ship was... skeleton crewed or something like that, because they were just maintenance crew...
Or, these ships could have been ready since a while, in the theory of the "outrunning the Alliance". That means it would have been a full sleeper ship, ready to launch if the Alliance did so.
That would mean probably a few more came in Sirius, as they probably would have jumped once the intel the alliance sleepers went out.
