'inverted' might be a slightly better descriptor than 'flipped', but still, my left hand is on the left in the mirror as well, but it's still the mirror person's right hand. and your distinction of 'real' vs 'conceptual' relative to paradoxes doesn't make sense. a paradox is real because it's conceptual, as paradoxes are relative to humans (or more generally, earthly life).
