Yes, fonts can reuse glyphs as part of other glyphs.
He's suggesting that it could be encoded in a more complex way 
through combinations, so that the rendering engine dynamically 
composes the glyphs from smaller things without font creators 
implementing anything manually or code points being used 
specifically for one combination.
However that would add a lot of complexity to font rendering and 
in reality anything that has to do with language is just as much 
arbitrary as it follows rules. We just prefer to look at the 
patterns.
