I thought that there is a separate HD transmitter which is usually combined
a common antenna, though in some cases they have a separate antenne too.
Although the center frequency is the same, there are two transmitters.
That being said, since the callsign is encoded into the data stream, I don't
understand why there is a requirement that the HD channel has to be
at all. Of course WZID in Manchester seems to revert to the string "HD"
Maybe that's why.
