In my math book, everywhere the author has used "non-ascending" instead of descending and "non-descending" instead of ascending.
I was wondering if there is some special meaning or use associated with it?
Because the way I see it is that it just increases the number of words and wastes ink.

Why do some authors use terms "non-ascending" and "non-descending" instead of ascending and descending?

The sequence 2, 2, 2, 3, 4 is not increasing, but it's non-decreasing.
The sequence 2, 3, 4, 5, 6 is both increasing and non-decreasing.
Compare the difference between "less than" and "not greater than."
(I have never seen the words ascending/descending used in this context but I imagine it's the same).
