That can normally implicate just how many 360° laps of phase occurs.

However, I suspect Jeff Joseph's XO phases fast enough where the routine measurement rounding ... smooths over the nightmare of massive break-up resembling ripple.

PS : I suspect THD would measure better than the same drivers in a more conventional XO by filtering out raw driver frequencies that misbehave more.
... just my 2¢
