Good question. The difference is a little bit tricky. If we just negated
each flag, we'd turn an expression like \(A \land B\) into \(\lnot A \land
\lnot B\). However, according to [De Morgan's laws](https://en.wikipedia.org/wiki/De_Morgan%27s_laws), the proper negation of
\lnot B\). However, according to <a href="https://en.wikipedia.org/wiki/De_Morgan%27s_laws">De Morgan's laws</a>, the proper negation of
\(A \land B\) is \(\lnot A \lor \lnot B\) (notice the use of "or" instead
of "and"). On the other hand, using an "exclude" bitfield negates the whole
conjunction, rather than the individual flags, and so gives us the result
