This is an excellent question! In the examples used in this article, I don't think that there is a difference. That said, I am now wondering if there might be situations where the two terms mean different things.
Perhaps the difference lies in the point of comparison? Mass is measured against opposing forces, whereas concentration is defined in relation to overall friendly dispositions? Concentrated forces can still lack sufficient mass, for example...
Plus, the Germans had air superiority. Airpower was crucial to Germany's early victories, as their opponents were largely fielding obsolete aircraft built by pacifists.
In the modern age, massed columns are a lot harder to pull off because massed artillery and tactical nukes can obliterate them.
For those examples what is the difference between Mass and Concentration?
