if your two hybrids have the exact same DNA, wouldnt that make them the exact same kind of plant? and if they dont have the same DNA, why isnt it possible to tell them apart?

They can have the same DNA but the registered names are different.
eg Dendrobium (speciosum x tetragonum) x (kingianum x tetragonum)= Jannine Banks
Dendrobium (speciosum x kingianum ) x tetragonum= Ku-Ring-Gai

Most people with a NOID are more interested in a name rather than a species background. If you simply want to know what species are in the background, most experienced breeders can take a good guess.
