I think there's some other mechanisms that wake CPUs? This is just saying, if something decided to idle the CPU, don't wake it just because there are tasks waiting to run (let something else decide to wake it). E.g., if the system is overloaded for some period of time maybe it will wake a cpu in response to that, but a short burst in tasks won't result in waking up all the CPUs.
