the top of the plate is surely the bit furthest away from you?

Perhaps not.
If the plates have, I don't know, pictures of ducks on them, they might have an absolute top, where the duck is the right way up, rather than a relative top as you've described. I was just wondering if this was the sort of stuff you thought about.
