Martin,
That is a valid question. Large Amalgam filings have a tendency to create fractures in teeth that often lead to full coverage restorations (crowns). This is done to protect the integrity of the nerve in the center of the tooth and bring the tooth back into its original function. If there is a gap (as we say open margin) between the Amalgam and the tooth structure then its safe to say there is leakage happening. When the tooth isn't sealed due to fracture, recurrent decay or failing filings, this allows bacteria to work its way under the filing and start destroying tooth structure. It is common practice to remove all the remaining defective filing (or restoration) to be certain that there is no decay left under the existing filing. A buildup is required after the amalgam is removed to give the tooth some structure to properly shape and hold a crown.
