No, they shouldn't. That's not how Emacs works. Instead, Emacs should process the directional tags and DTRT. This (i.e. display of marked-up bidirectional text) is not yet supported, but OTOH no one requested that yet. (Well, actually, one person did, several years ago, but I never heard from him since.) Inserting into buffer text something that wasn't there to begin with is asking for trouble: sooner or later that something will leak to the disk, and users will rightfully complain that Emacs corrupts their files.
