That's what they meant then by it doesn't matter if you say the size of the grid (and the space between the hash marks) is increasing or you say the size of your measuring stick is decreasing, because the end result is identical, so neither is "more true" than the other, just that space expanding fits into our brains better.

EDIT: This even moreso: http://math.ucr.edu/home/baez/physic...GR/hubble.html
