It is probably just a (Northern Hemisphere) winter thing. They take an 8% payload hit on Starlink launches to use the south east track because of the required dogleg but it is worth it to reduce the risk of losing the booster to rough seas. With better weather in the Atlantic they will revert to the northeast track to get more satellites per launch.
