The storage overlay does not pertain to the PLO. It pertains to the entire element not being immediately removed from any type of use. Just because you removed the element from the chain does not mean it's not in use somewhere. You can't even say how long the element may be in use (e.g. task does not get any CPU because of CPU load or swapped out address space in multi-address space serialization).
