I really can't follow your comment and I've been trying. Would you mind a longer explanation of what you're getting at here?
They mean 125um = sqrt(a*b), where a is the Planck length* and b the size of the observable universe (I didn't verify). Implying, 125um is some sort of middle ground. *Often said to be the smallest length with physical meaning.
