A negative response to the second clause of the definition (sharing affection, influence, common interests, obligation) would negate the need to list anyone, even if a positive response is given for close/continuing contact–at least that’s how a lot of people interpret it. You can have close/continuing contact with a foreign national but if you believe you don’t share affection, influence, common interests, or obligation, you (in theory) wouldn’t be lying if you answered ‘no’ on the SF86.
I think what @fed-investigator means to say is that our overall pretty logical interpretation of what a constitutes a foreign contact differs from what is asked for on the SF86, and we should probably address that.
