There's a subtle difference here. A "block box" in the spec is a block-level box, while a "block container" is a box whose children are either all inline-level boxes in an IFC, or all block-level boxes participating in a BFC. Notably, an "inline-block" box is a "block container" but not a "block box" since it is itself inline-level.
