If all three of you have disable mutual friends, Facebook can't make the connection that you are mutual friends, so it will say none possible.
If Bill, Fred and Sam are all Friends with each other, and all 3 have Mutual friends enabled, all 3 will see 3 mutual friends.
If Bill disables Mutual friends, Fred and Sam will see Fred and Sam in Mutual friends, but not Bill, Bill won't have any Mutual Friends
If all 3 disable Mutual Friends, no-one will see any Mutual Friends
