Hi Chris while awaiting the correct answer from the other Jeff, here is what I think. Slag in well worked steel forms long thin strings "stringers" which will give the effect you mention. In wootz working the steel in a similar fashion would eliminate the watered pattern. Therefore large (unworked) inclusions of slag would provide a fracture line.
Hope I am correct
