They probably did completely cut some teams entirely but also kept some entire teams deemed critical (or maybe that's the ones they want to return). Besides that it generally comes down to instructing every group to pick out X percent (in this case 50) to cut and get it done. I've been at places where they did the required layoffs even in critical groups that never stopped hiring people and had to even step up hiring afterwards.
