In CPU pinning, the threads do not leave the assigned CPU-cores. So this is not exactly CPU pinning, it is a new "trusted" thread group scheduling implemented through cgroups where threads can move around CPU-cores as long as they end up in "trusted" groups of threads/processes. So, if two non trusted threads are to be scheduled, they won't be in the same CPU-core/CPU/resource/etc. * Edited for clarification
