  It does. Each color band in the classically-colored Mandebrot set (which
is what is used in the video) represents one iteration. Now count how many
distinct color bands there are in the entire video (I have no idea, but
I'm guessing it's in the millions).

  It's more like you don't *need* so many iterations for a 2^30 zoom to
look good as you need for a 2^70 zoom. You *could* use the larger amount
of iterations also for the 2^30 zoom, but it would change very little
(only pixels adjacent to the set would probably get different coloring).
