That's a much more complicated story than that...
The flasks were made by Norris Powell of 'sanderianum'. The Orchid Zone had bloomed and pictured Deep Pockets and Jacob's Ladder, though the cross did not take... So they bought back from Norris Powell flasks....
They started to be released around 1993-1994. I bloomed mine around 1996+, and the Taiwanese not short after, maybe a year later. The Orchid Zone at first denied the first hybrid blooms as being from their 'sanderianum', but when masses bloomed everywhere, they had to acknowledge it was indeed a hybrid, on a case by case basis ( kind of, if you did not bloom them, it might be sanderianum after all...).
Most of the wholesale customers asked back then for their money back, one of the largest being Ching Hua Orchids at that time. This said, the whole chain made a lot of money, as many hobbyists had killed theirs, and did not claim the money. The retail sellers usually refunded/accepted claims only if the plant had bloomed, even if they knew it was not a sanderianum.
On the side of the Orchid Zone, it was their main commercial income, so they offered to the wholesalers to deduct the sanderianum purchase from their future purchases, over time, as a percentage. Can't remember if it was 10 or 20% each time they were buying.
Some of those wholesalers told me an interesting story, in that 'divisions' or selected plants would be overpriced, and the deduction would be applied. Which means not so much of a financial loss.
Like the urbanianum in Europe and the victoria-mariae, the sanderianum was a punishment too for lying to their customers, and saying it is Deep Pockets x Jacob's Ladder, where in fact they were purchased from Norris Powell as generic sanderianum flasks... and subsequently proliferated, as those did clump readily in flask...
