Not exactly.
The flag_values (and the flag variable) are usually an array of bytes, 
not a comma separated string.
The flag_meanings need to be something like 
"One_or_more_measurements_are_back_filled_from_the_spacecraft_recorder 
Packet_time_is_in_the_future Packet_time_is_older_than_the_threshold".
The number of flag_values must equal the number of flag_meanings.

Those are terms from the CF standard. See 
http://cfconventions.org/1.6.html#flags for details.

It might be better to direct future questions about them to the CF 
mailing list.
