Facebook privacy - wall posts in friends' news feeds?

[pinacoladaxb]

One of the options under the privacy settings is as follows:

Posting to someone's Wall may appear in your mutual friends' News Feeds.
Show Wall posts? (checkbox)

Does that mean that, if checked, my friends will only see what I write on other peoples walls if they are friends with both me and that person?

Yes. It will only show up on their news feed if the wall to wall is between mutual friends
