    No, you still got it wrong:

    1. 'n' fragments are generated for a triangle without backface culling.
    2. 'n' fragments are generated for a triangle with backface culling if the triangle is determined to be front facing.
    3. '0' fragments are generated for a triangle with backface culling if the triangle is determined to be back facing.

    You never ever get two faces being rasterized for a single incoming triangle.
