Certainly they're not taking winds into account six months in advance.
But, in the context of just overall historic data, I guess it makes sense. It just seems like such an outsized difference for such a short flight. By comparison, if you extend the same difference out to a longer transcon flight, it would be like one flight booked at 5 hours and the next at 5h45.
