I think their use case here is an AP that (they presume) is talking
directly to the client. In which case it's probably a fair assumption...
Most operating systems don't drop packets between the WiFi card and the
TCP stack :)

Of course, a client may be forwarding the packet somewhere, in which
case this would probably break in interesting ways...
