Well, to be more precise:
the reference stall speed is different but the
resultant safety is equivalent ... since I believe at least some Airbus products are using Vsr and reduced reference speeds by means of a finding of equivalent safety, since they predate the actual adoption of Vsr by rule.
It's not necessarily true that 1.23Vsr=1.3Vso for a specific type - it all depends exactly how the cert was done.
(As indeed also applies to our products)
