They mispoke, it has to be removed in a specified time frame after the illegal content is reported; not after someone posts it.
Just like if someone was running through a back ally, tossed something illegal in someone's yard, and then days later reported finding it. That person wasn't hiding the item or their knowledge of the item; they just hadn't found it yet and thats not going to be held against the yard owner.
edit: even saying reported is incorrect, its when its discovered. If you were going through and found something obviously illegal you would be required to report it just like anything else illegal; you couldn't find it and then just be like, "Ah well no one has reported it yet not my problem!"
