This junction was originally mislabeled as a Complex Roundabout, or CRAB, even though there is no roundabout loop. The tracks on split before they merge so trains are less likely to encounter a red signal. It does not give preference towards any track.

It is a complicated version of the Star Junction, with the branches very long and intertwined. A larger Star junction will have the same effect.
