Precisely - and the more breeding goes on in a given group, the harder and harder it can become to tell them apart by eye (because with breeding, you're usually aiming towards a standard, like a big round dinnerplate of a flower of a particular colour); if you look at the so-called
Complex Paphiopedilums or
Photo Gallery Paph Complex 1 for instance, within a breeding line they sort of start to all blend towards something that looks pretty much the same to most people (unlike the
primary hybrids) - even if two particular similar looking plants actually have quite different ancestry. Phalaenopsis are also probably approaching this, where one large plain pink phal is much like another. Of course, given the huge amount of meristem culture that goes on in this group, quite a lot of phals that look the same as another one
might well be the same thing.
In this case, a genetic test (between a NOID and a named plant) might be feasible, but as I have no idea how varied phalaenopsis genetics are, I have no idea what the appropriate tests might be!
(Indeed you could feasibly end up with two plants with different ancestry with essentially the same mix of [functional] genes, but to an orchid hybridiser, they are not the same; still there should be techniques that would prove, beyond a reasonable doubt, that they are clones). This also doesn't take into account various epigenetic factors in phenotypic expression.
