not true. the
registration form clearly asks which one is the seed parent, and which one is the pollen parent, and the registration database records this information. see the entry for
Catasetum Mrudula for an example. Many growers will label the reciprocal cross as if it were the same thing, but it is more properly considered a different hybrid.
There are several cases where both A x B and B x A have been registered under different names. There was a recent post on this board which mentioned an example of this, but I can't find the post.
The reason for allowing this is that plastid DNA (found outside the cell nucleus - such as the DNA in chloroplasts and mitochondria) is inherited only from the seed parent, so a cross is guaranteed to be more genetically similar to that parent.
