I'm not that "up" on cover crops, but i think the info you're seeing about cover crops which are planted in the spring would pertain to large scale agriculture/farmers who arent going to plant something in that field till later in the year, or maybe not at all that year. The majority of us gardeners would do a cover crop in the fall, to keep the empty soil covered until we're ready to use it for those veggies in the spring.
