Ok, I guess I have phrased my question incorrectly. Article shows that cross "in focus" had purple fringing and slightly defocused one had green fringing, after that it is stated that:
"The other colors of the spectrum are left defocused and add up to a magenta fringe. For this reason purple fringing is more common than green fringing".
Can it be that purple fringing was because the cross was slightly defocused as well, but it was on the other side of the focal plane? Like in popo's sample pictures a few posts above.
