Gotcha, that is interesting. Guessing they are Block 5 boosters that can be used many times, and the center core uses recycled older version pieces.
Well, with limited re-usability there will be some boosters better than others and there will be end of life.
So once they're on their last legs* they can get RID** of the booster as the expendable core of a Falcon Heavy launch.
