I think when he said "constellations are a match" it was referring to the predicted visible constellations that would be visible if they'd jumped into the point in space they were intending to, not a comparison to what was seen on Cobol. It was just a cross-reference of a successful jump and to verify they hadn't screwed up and gotten off-course. At least that's how I took it.
