I am not John, but this may be the explanation:
The RX02 uses double density only for the data inside the sector. The
sector header is (mostly) the same as a RX01 sector header and it is
rcorded in single density. Result: A RX01 holds 128 Bytes per sector, a
RX02 holds 256 bytes per sector, thus doubling the capacity. So the
floppy controller has to switch the data rate from sector header to
sector data... A really, uhhm, "interresting" design.
