Hardiness/Reinforced Armor Masteries name mixup?

Have these two masteries been mixed up somehow? I feel like they have been.

Why does the skill Hardiness give extra armor while Reinforced Armor reduces damage from crits? Should this not be the other way around to feel more natural? Reinforced Armor giving more armor sounds right, Hardiness reducing crit damage sound right.

Anyone else feel this way? Or is there something here that I'm not seeing?
