Sure, that's why I said that I can't know for sure - because it's a sentence that can be used truthfully or it can be used as a polite lie.
I just feel that if it were possible to track every time that sentence is said it would probably be significantly more often used as a polite excuse rather than as a truthful statement. (And even then, that's my gut feeling / assumption, I may even be wrong about which use is more common).
