I think "changing the proposed building cap to feature a more distinctive design" means allowing the design they've submitted... the glass box. It looks like a finished render to me, and it is clearly the taller addition to the earlier rendering. I don't know that it qualifies as "distinctive" but maybe somebody else thinks it does. Subjective opinion.

If anyone is familiar with the history of renderings submitted for Central Park Tower in New York, many people thought the render submitted was just a massing model. It wasn't... it was pretty much what is now being built.
