Unlikely that Silca does that. What they probably were saying that they could see the tool marks where the screws had been removed. Tightening the screws leaves marks on one side of the screw, and loosening would leave marks on the other side.
Related: If you're buying a used car that uses rubber timing belts, and don't have solid documentation¹ that the belt was ever changed, you can look for tool marks on the timing cover bolts.
¹ There are people who will buy the timing belt parts kit then return it, in order to have a receipt to show prospective buyers that the work "had been done".

You can also just check the condition of the belt. Checking timing bolts for wear is not going to be an accurate measure of if the belt was replaced. (what if they had a head gasket replaced?)
