The simplest answer is it may not be. Too much headspace is the common reason for food spoilage in canning. It permits too much oxygen in the jar which promotes the growth of pathogens such as botulism. Canning really is a scientific art. If the recipe calls for 1/4 inch headspace, leave 1/4 inch headspace. Nothing more.
