Things become a bit more fuzzy when about first, second, etc. I mean, dimension-41 tries to go 42, with the addition of 1, but, it ends up as 411 by not being able to reasonably add 1 to go any further; similarly with dimension-44 going to 42, by subtracting 1, but with the dimension-42 as the 43rd dimension, and, so, it ends up as 441.
