AABB Collision Doesn't Line Up

I've been following this for AABB collisions and translated it to 3D. However, I've found that the collision math doesn't work, and two boxes defined like this:

    struct AABB player = {
        .position = {10, 7, 10},
        .half = {1.5, 1.5, 1.5} // 3^3 box
    };

    struct AABB box = {
        .position = {10, 5, 10},
        .half = {0.5, 0.5, 0.5} // 1^3 box
    };

are said to not be colliding, when obviously, a 3x3x3 player should collide with a 1x1x1 box when the player is only 2 units above the other box. You can run and see the code here, where the result is not expected: https://godbolt.org/z/o9fMWodvT

Any idea why the collision detection isn't working properly would be greatly appreciated.
