Yeah: technically, that's true. But consider that if you've conscientiously taken the other procedural steps, including the one of pointing the gun away from anything you wouldn't want to destroy, it's an acceptable and safe exception (such as dry-firing). Another thing you can add to the "ritual" of cleaning and disassembly (and that's how I prefer to think of it) is to verify the negative status of any loaded-chamber indicator your pistol has. Some use a white dot, others a colored flange, etc. but it's a smart thing to do as well.
