I'm not sure. I read that as rounding because the calendar year doesn't get divided evenly by a fixed number of calendar days.
The current system is desingned to keep our dates sync'd to where the planet is in relation to the sun. We round so we always are at point X and a certain calendar date....but if the good doctor is right, the Earth's axial tilt doesn't follow it. Assuming he's right, one day July 1 will not be in summertime, leap year introductions or not.
Until we find a planet that has a "day" than can always always always be divided evenly into it's "days in a year" number, youre right, we can't do that. But none of our definitions has ever worked for that purpose.
