The complete sequence of leaders then seems to be a form of tabulation (sort of whitespacing), and default ignorable, unlike the full stop which is a non ignorable punctuation (or a non ignorable decimal separator). Also the sequence of 3 one-dot leaders is not completely an ellipsis punctuation, because many typesettings include a tiny space after the ellipsis (or after the full dot), this thin space being absent from the isolated leader. The ellipsis is always a word or token separator, unlike the the full dot which maybe part of the same token (for example a decimal or floating or exponential number). So one-dot leaders can safely be replaced by spaces without affecting the semantic, unlike the full stop or the ellipsis.
