For uneducated half wits.

If they keep looking they might also discover that the Sun's magnetic
field flips with the sunspot cycle.

Yet more old knowledge rediscovered by breathless half wits that don't
bother to read the existing literature and announced in a breathless
press release.

  To drag the topic back to actual physics- does the surface rotation or the magnetic field axis maintain a constant direction on space?

You mean other than the regular reversal with every sunspot cycle?

  Yes, other than that. AIUI what we call surface rotation is inferred by tracking sunspots, but the Sun's magnetic field is (currently thought to be) mostly generated in the shear zone at the bottom of the convection zone where the core's more-or-less coherent solid-body-like rotation gives way to messy vertical motion in the convective layer.

  I'd expect the core's spin axis to remain constant in space.

  It would seem to me therefore that sunspot motion doesn't really tell us anything about the rotation rate of any part of the Sun other than the shear zone. Sorry, "tachocline". I just looked it up.

  So, ignoring sunspots, I see no clear way to determine the rotation of the surface.

  I also see no reason that the tachocline should have an overall angular momentum *to* conserve- what it has is parasitized from the core.

The Sun is not featureless, uniform ball with occasional spots.

My understanding of the abstract is that the surface rotation has one rotational axis 
but an overall tilt in the suns magnetic field away from the surface rotational axis in 
the data has been revealed by some sort of complex data reduction. And that the 
rotation period of this tilted magnetic field is the same at both the poles and the equator, 
contrary to the variable rate of surface rotation.  Indicating that the current dynamo 
models for the sun are incorrect. 
I believe the tilt in the earths magnetic field relative to our rotational axis is caused
by an irregular shaped core that wobbles as it rotates creating an asymetric rotation
axis in the earths liquid core and in turn creating an overall tilt in earths magnetic
field. Maybe this papers' findings indicate the same for the sun.

Seperately, the abstract also suggests data other than just sunspot motion is used to 
determine surface  rotation speeds, but its not clear what data. Need the full paper 
for that.

    One would expect the net rotational axis of the sun to point in a
    direction fixed on the background stars, however, one would also
    expect a complex precession of the net rotational axis due to Jupiter
    and the other planets, major and minor.
