I think what hes saying is that if you're only allowed ten numbers you could write

1, 2, 3, 4, 5, 6, 7, 8, 9, 10
or
1, 3, 5, 7, 9, 11, 13, 15, 17, 19

You still have the same number of pieces of data but have spread them over a greater range.

Of course in an image if you did something as simple as that you'd end up with some pretty ugly posterization. With a longer sequence of numbers though they might come up with something clever that extends the range a bit but is subtle enough that the gaps aren't overly noticeable. No idea or if they've done any such thing though.
