Mark, you may be interested in this article just published by the same author:
"Molecular markers presented clear evidence that A. senescens subsp. glaucum is in the strict sense only distantly related to A. senescens and should be accepted at species rank. As the binomen A. glaucum refers to the A. schoenoprasum alliance, the name A. baicalense must be applied."

Wow, that's hot off the press, published January 23, 2018, just one week ago! Thanks for pointing it out. Too funny, it was Nikolai Friesen who elevated Allium glaucum to A. senescens ssp. glaucum twenty years ago, now he's changed his mind, lol. I'll see if there's a free download of this, or ask Dr. Friesen himself to send me a copy. It takes ages for these types of small singular publications and name changes to make it into the body-work of taxonomy.
However, the important thing to note, all that goes around as the dwarf "circle onion" named A. senescens ssp. glaucum (of Hort.) still have nothing to do with the true tall plant, whether it was for 20 years the true A. senescens ssp. glaucum or whether they have resurrected the old name baicalense (generally regarded as a synonym of asian A. senescens along with 22 other synonyms). These taxonomists create as much of a quagmire as they do any enlightenment).
