Clip and children: property redundanz in full hierarchy

HiIn the full hierarchy view there are:

Clip: clipNumber, partOfEpisode, partOfSeason, partOfSeries, position, publication  

 
 
 RadioClip: partOfSeason, partOfSeries   

 
 
 TVClip: partOfSeason, partOfSeries, partOfTVSeries  If Clip has already partOfSeason, partOfSeries, does it mean, that RadioClip and TVClip must not repeat them?

In the own view of RadioClip and TVClip it is correct - RadioClip has nothing, and TVClip has only partOfTVSeries.
