A more important difference is that affirmative action is generally used to favor under-represented demographics (or equivalently, to disfavor over-represented demographics). In this case it looks like they disfavored women while they were already under-represented! I'm not quite sure of this but that's what another article [1] suggests:
In 2010, before the measure was allegedly introduced, female student participation was about 40%.
The newspaper reported that after the two-round application process earlier this year, only 30 female applicants were accepted to study, versus 141 men.
