Urethane varnish turns yellow with age and it is fairly yellow to begin with. Whoever advised that amber shellac was needed beneath seems to have failed to remember these facts.

Secondly, it makes no sense to undercoat a finish where you are striving for durability with one that is less durable. I'll bet with testing it will turn out that the impact resistance of urethane undercoated with shellac is less than urethane only.
