I would assume so, but as far as I know on Earth, we tend to find two distinct dip poles roughly equivalent to a north and south pole (i.e., one with a +90 inclination and one with a -90 inclination). You might expect that during a geomagnetic reversal (which is often described as a weakening/temporary collapse of the dipole component and thus a relative strengthening of the higher order field components) you could have more than one pair of dip poles, maybe?
