This is a much better way of understanding things. 2003 UB313 ("Xena") possesses all the characteristics that people judge Pluto to require to be a planet; it too has at least one tiny satellite (S/2005 (2003 UB313) 1, nicknamed "Gabrielle"), it is larger than Pluto and part of its orbit actually brings it closer to the Sun than Neptune.

Indeed, the asteroid Ceres (which can be considered a dwarf planet) was considered a planet for some time after its discovery. One might say that Pluto has been considered a planet for so long because it was too far away for anyone to be able to prove otherwise.
