Uhm, quick but: Apparently some browsers (OK, one, and we all know which one) embraces & extends the DNS in such a way that this provides the fall-back behaviour you seem to expect. But this is not standard and it won't fly with most software. I checked. It doesn't in Firefox/IceCat. Even if it does in current Chrom{e,ium}, it might just be an unreliable side-effect.
