I can't remember who wrote this line, but it was borrowed from the
--analyze-in-stages description.  The point is that if you use
--analyze-in-stages without --missing-stats-only, there will be a period
where existing statistics will be replaced with ones generated with lower
statistics targets.  Obviously, this wording isn't clear enough.  We might
need to either remove that sentence or add "When used in conjunction with
--analyze-in-stages..."
