Does the Earth rotate clockwise or anticlockwise?
If you are floating above the north pole of Earth you would see the Earth rotating anticlockwise(*) if you were floating above the south pole, you would see the Earth rotating clockwise.

So the direction of rotation depends on the point of view. You're going to find that many of the truths we cling to depend greatly on our own point of view...
You could say "I'll take the North Pole view". Now how do we define "North Pole" on a pulsar (which is many many times smoother than a billiard ball). One way to define "North Pole" is "the pole from which a an object appears to rotate anticlockwise". Can you see how the definition is going round in circles?
Or you can define "North Pole" in terms of magnetic field. The North pole of the Earth has a magnetic pole (that attracts the North-seeking pole of a compass) You can try to define the "North Pole" of a pulsar in terms of that which has the magnetic pole which corresponds to the that near the North pole of Earth.
The rotation of a pulsar is unrelated to its magnetic field. 50% of pulsars rotate clockwise about their North magnetic pole, and 50% rotate anticlockwise. The rotational direction of a pulsar is derived from the angular momentum of the star from which it is derived. The magnetic field is also inherited from the star. But a star can swap its magnetic field without changing its rotational direction.
There is no preferred direction of rotation, so a pulsar is equally likely to rotate clockwise as anticlockwise.
(*) and so the shadow of the gnomon of a sundial rotates clockwise, and clocks which were made by northern hemisphere horologists follow the convention. If the technological revolution had occurred in Patagonia not Europe, clocks might be very different.
