I am not sure that is true today. When restorations were cemented it was
absolutely required. Let's say there is a restoration that is bonded in
place, and it is absolutely solid with no decay under it.

Why end the crown margin BELOW the restoration?

Oh its good to end on solid tooth but is it absolutely essential? Maybe not.
If the crown design further weakens the tooth in trying to accomplish that,
what is gained?
