His passive only takes into account bonus MS. If he is slowed by Sejuani while he is at his base movement speed (320), he will not lose any AD, as his passive isn't granting ANY bonus AD.

His bonuses would be unnafected by slows (increasing with haste, decreasing with slows) if the tooltip read "Gains AD equal to X% of his maximum movement speed."
