Indeed, that. But we can blame Digital Anvil for that, since I've read somewhere that Sirius Sector was initially named after Sirius which was to be somewhere in the middle of the area. Initial positions for the systems was also quite quirky, e.g. Liberty being around Crow Nebula (what might be explanation about Freeport 7 we know now). Kusari was placed roughly between Lower Barrier and Walker, Bretonia in the Barrier(?) and Taus and Rheinland across area we know as Omicrons (more or less, but not that big into it).
