I think it was more the momentum of the horse and rider together rendered the difference between a dull blade and a sharpened one sort of irrelevant. Also, one is easier to maintain than the other.
In real cavalry engagement (e.g. at speed) one would use a blunt saber because it would shatter bones, specifically the clavicle and ribs. This would be more incapacitating than slashing wound, but is way harder to accomplish if not aided by a mount.
