No, not the quarter. The text is right to use "month". ITU-R TF.460
allows for a leap second on the last day of *any* month. That's
another point in favor of including a reference to the official
document.
Perhaps the original point was that when the LI is 0 then the last
minute of the month should default to 60 seconds?
