Of course it's not a monopole, but the dipole idea is also too simplistic, as is the idea of "poles". Presumably, the dipole moment of the Sun has become very small but there are still higher orders at work. Thus, the field of the Sun will look very much more complex than the simple dipole field [0].
A possible configuration would be that both geographicals poles of the same sign, but the field around the equator is of a different sign, like a quadrupole perhaps.

Correct. I'll do some digging around to find the polarity maps we have around the lab here and post them if I find them. At times, there really isn't a clear 'pole' of the sun, and octopoles can sometimes be found.
E: Here's a link to one of those maps. I'll see if I can find any better.
