I dont get it at all.

OP wants his image converted to pure black and white, but without loosing the antialiasing, right ?

Your Threshold action produces a selection ?

On a black line, the threshold selects only the anti-aliasing pixels. The fully black part of the line is not selected, all you get for a black line is two thin parallel lines corresponding to the edges. The threshold extracts the grey patches plus the anti-aliasing. Then, the Erode step removes the thin lines, so you are left with just the grey patches...
