Approximately yes (still very expensive), and that's a sister plant of 'Taka', a pot plant hybrid made by Orchideen Wichmann... Taka is absolutely sterile, like the others from this crop, as they are aneuploids hybrids. I witnessed that story (same for Atlas, etc... they are from Wichmann) and know who had the idea and who did that ( the same that did the rothschildianum album).
Those Sedenii, Schroderae, Albopurpureum, I do not know exactly about this cultivars, but I know as a fact that Michel Paul, through Mike Tibbs, sold hundreds of divisions ( including the old RHS awarded ones) to California, including Orchids of Los Osos in the 90's.
After that, Glenn got a batch of plants from another nursery in the Netherlands of phrags, some with proper parentage, some not so let's say, and still related to those people ( one RHS judge, and another one vice chairman at a point of the Netherlands Commercial Orchid Growers Association, so we would think they can be trusted).
Many were, of course not properly labeled. Many of those hybrids, like Sedenii, Schroderae, came nearly all from Europe, and were not remade until the end of the 90's-2000. Some could never be successfully remade like the old ones too.
That's a very nice Schroderae you have definitely, but it is not Sedenii... I tend to think that it is a pure Schroderae actually, not one of its hybrids.
Thanks for the clarifications.
