Not necessarily. It could be smart enough to know what you meant (and indeed to deduce the entire history of your thoughts!) and simply not care, because you told it to care about something else.
For example, maybe you inadvertently programmed it to "be totally literally 100% certain that you've completed the task I told you to do". Then from its perspective, there's always a tiny, tiny chance that its sensors are being fooled or malfunctioning, so it can't be literally 100% certain that it's ever made a paperclip successfully, so by your programming, it should keep making more paperclips. This is independent of whether or not you wanted it to do that: it's a result of what you programmed it to do and what you told it to do.
