It is in error? Let me quote something:

# Radio buttons in sets where none of the buttons are marked as checked
# must all be initially left unchecked by the UA (which differs from
# the behavior described in [RFC1866], but more accurately represents
# common implementation and author needs).

(That it is considered "very poor UI" is nice, but not really that will 
scare away authors.)

If you allow them to be unchecked initially and a user accidently checks 
one which needs to be unchecked for that particular user he/she has a 
problem. The current description would allow that to happen.
