I’d like to add that sometimes definitions do matter, particularly in a public settings such as a blog. Even if t3tsubo and Benquo agree with both (a) and (b), it is possible that others reading the OP think that it is asserting (not-a).
If a significant number of people reading the blog are likely to think that it is asserting (not-a), rather than asserting (b), then it may be worth clarifying the OP to ensure that the correct message is received. I don’t know whether this would be a common misunderstanding, I can only conclude that at least one person read the post as asserting (not-a).
Good summary.

That is a good point.
