As mentions, if someone is still on the initial release of High Sierra (10.13), and installs the patch, then later updates to 10.13.1, then the security flaw will return.

It's hardly impossible, but it could leave people insecure even if they think they've installed patches the right way, and probably explains why (when they can) companies wait for more testing before rolling out a patch.
