It's not 35%+65% = 100% CC reduction. Merc treads reduce CC duration by 35%, or another words to 65%. Cleanse then reduces that remaining 65% by 65%, for an additional 42.25% reduction in duration. The CC will stick stick to you and last 22.75% of the duration. So while the 2 sec stun now lasts only 0.4 sec, it still interrupts channeled abilities.
