In this case I think it does show resemblance to Brassavola subulifolia, so it could be B. Little Stars (nodosa x subulifolia) or a hybrid from it. These 2 species and a couple other Brassavola species, and the various hybrids among them, can be so similar in appearance that it is may not be possible to conclusively distinguish between them from a photograph, and there certainly are some out there that are misidentified.
