16 vs 10

Acording to the Ill. 18 the point of standing on 16 vs 10 is TC 0 (Hi/Lo).

What is the logic behind this number?

I realize that I'm more likely to bust when the count exceeds 0, but that is the same when the dealer have i.e. 8 or 7 as well. And here there is no number(Or it's to high to mention).

Thank you
