This isn't really accurate - the root cgroup is a cgroup like all the others. More accurate would be something like:
Since every task is always a member of exactly one cgroup in each mounted hierarchy, to remove a task from its current cgroup you must move it into a new cgroup (possibly the root cgroup) by writing to the new cgroup's tasks file.
