Yes those holes belong there. These screws are intended to anchor the block down to the little shelves, (called "cornices"), on each side in the same manor that Steinway uses dowels. If the screws do not go all the way through the old block or there were no screws installed at all then I would strongly suspect a manufacture defect. Not all grands, particularly cheap ones have these. It could also be that someone replaced this block once before and neglected to reinstall the screws which would explain why the holes had threads but no screws.
