In the following scenario, does the barbarian get the extra 1[W] damage from rage of thunder hooves?
Pressing Strike At-Will Standard Action Melee Weapon Target: One Creature Keywords: Primal, Weapon Effect: Before the attack, you shift 2 squares. You can move through an enemy's space during the shift but you can't end there. Attack: Strength vs. AC Hit: 1[W] + Str modifier damage, and you push the target 1 square. If you are raging, the attack deals 1d6 extra damage. Thunder Hooves Rages Daily Standard Action Melee Weapon Target: One Creature Keywords: Primal, Rage, Weapon Attack: Strength vs. AC Hit: 3[W] + Str modifier damage. Miss: Half damage. Effect: You enter the rage of the thunder hooves. Until the rage ends, you can move through one or two enemies' spaces during each of your turns. When you move through an enemy's space, your next attack against that enemy during the same turn deals 1[W] extra Damage.
Key: _: Empty space L: Part of large monster W: Wall B: Barbarian

Scenario: The barbarian uses Thunder Hooves rage (granting him rage of thunder hooves), then uses Pressing Strike and shifts south one square, then east one square.
Observation: It almost seems like the barbarian should have to move entirely through the monster (the same way you would calculate flanking) in order to get this bonus, on the other hand the barbarian would be moving through part of the monster's occupied space.
