Of course they do. You should not assume that everyone has already bought every bundle ever released, those people to have a right to get these games in a Bundle.
And since it’s pay-what-you-want, do whatever feels right for you.
As far as i’m concerned, I give way less when a bunch of game I already own are included (and it almost never happens anyway, the re-hashes are most often part of the bonus games added one week after the release)
