::Yes, that seems to be it.  Is it worth a sentence of explanation?  only one of the nine or so uses mentioned in Saltire#Other uses is actually a Saltire, and this usage seems more worthy of inclusion than most of them ... or alternatively perhaps the Other uses section should be considerably culled, before someone adds the letters X and x and the Greek letters Χ and χ, claiming that they are all Saltires, in spite of them all considerably pre-dating Christianity ;-)
