Triangle face not showing up

Hi all,
Consider the following triangle list layout:

i    [1] - [3]
^     |  \  |
|    [0] - [2]
|
|__ __> j

and vertex indices

Triangle 0 indices:  2 - 1 - 0
Triangle 1 indices:  3 - 1 - 2

and face culling VK_FRONT_FACE_CLOCKWISE, why is only triangle 0 (vertices 0-1-2) showing up, given that both face normals should be facing towards the same direction?

PS: culling is clockwise, but both faces are ordered COUNTER_CLOCKWISE, so why is face 0 even showing up?

// vertices uniformsn(vec3 pos, vec3 color)
    {{-0.5f, -0.5f, 0.0f}, {1.0f, 0.0f, 0.0f}},
    {{-0.5f,  0.5f, 0.0f}, {1.0f, 1.0f, 1.0f}},
    {{ 0.5f, -0.5f, 0.0f}, {0.0f, 1.0f, 0.0f}},
    {{ 0.5f,  0.5f, 0.0f}, {0.0f, 1.0f, 1.0f}},
