Just thinking about this some more. The Diaspora Fleet travelled for 12 years and got caught in the Slipstream which accelerated them even more and made a journey back something they couldn't consider. They were in flat space so were travelling slower than light until they got caught in the slipstream. If they were travelling STL, even if they could get up to near light speed, Kua wouldn't be far away (12 light years) until you throw in the curve ball of multiple years in the slipstream.
It's entirely possible that it could be Kua on the map as a result, but they haven't a slipstream route to even consider travelling back. Bear in mind that the portals don't necessarily connect systems nearby each other. Looking at the star arrangements on the map, it doesn't look like the Third Horizon's patterns but I could be wrong, especially as those maps are a chain of portal connections.
Alternatively, they could just have named a star 'Kua' as a memory of home, kind of like many British place names are repeated in former colonies.
