Yes, these tufts seem a bit long. But in any case, you can average their angle to the centerline and in doing so, one can indeed see the flow on top of the fuselage from left to right - a clear indication of the Coriolis Effect on the airflow, which is also probably why the US voted for the right-wing candidate in the recent election.
