I believe it's because you had such a big advantage that you were still above the threshold that marks a move as reviewable.
From the intro to the feature:
"A move that changes the evaluation by +1 is considered a mistake on an equal position, but not so much if the position was already won or lost. In this case, the evaluation swing must be more important to be considered worth reviewing."
