Highlights become blocked when the exposure and development is so extreme that the highlight areas begin to loose contrast / separation / detail in the negative itself.

Compensation though purposefully compresses the highlights (in essence partially blocking them up by forcing the film to shoulder early). Compensation is used as a compromise so that burning can be avoided.

Both methods are workable but better contrast in the highlights is generally available with burning because there is better separation of tones on the negative.
