Doh' I was confused.  There is a difference between

0018 50 ff00 ... and
0018 50 ff01 ...

I think we can now say that for "short commands" of the form

0018 XX ffYY....

YY is a subcode that selects a certain command from a group.  Probably we
are already seeing legacy cruft and backward compatibility issues here (even
though netmd is a new protocol, maybe it is internally revised).

Thanks,
