Yes they are, I tried to illustrate it. Think of when the quota if fulfilled; I have a job pool of 20 jobs. So far I have filled 10 slots with mails and 5 with females. In order to follow the quota I would have to auto select 5 women, regardless of the qualifications of the remaining male/female applicants.
If any of those 5 remaining slots were better suited by male applicants (by qualifications or other quantifiable metrics) they were turned down as a result of discrimination.
