That means the hungry ghost of such an individual will be more powerful, and may have a few themed powers. But the po is the seat of power. That's where the Enlightenment goes, no matter what it is.
Incidentally, this means the idea that you give more powerful people more lavish funerals in Creation is not a kleptocratic abuse but is instead a good social adaptation.
After all, a mortal's hungry ghost can be dealt with by a trained exorcist. It's an annoyance, but it can be handled. By contrast, the outcaste dragonblood prince of a threshold nation might leave a hungry ghost that can't be stopped by anyone local. Thus, building them a big pyramid is a sound investment, if it stops their monstrous ghost from appearing at the feast after their successor is crowned and laying waste to the place.
That sort of thing really puts people off their food.
