Heads up it doesn't just mean literally one line it means any page that is insufficient info. If it doesn't provide enough info to justify how the character fits here than it's one-line so no more edit warring on it due to having more than one literal line. This has been pointed out more than once in edit summaries on how it works but you seem to take it literally which isn't the case it's merely a term used here.
