Yes ..that is what the leakdown test would tell him. It would also tell him if it was an intake or exhaust valve problem. Might want to ask him that.
A leak test can verify ring, intake valve , exhaust valve, head gasket, etc.
So, he has determined you have a burnt valve, but it could also be a stuck valve or bad quide. Alarge % loss does indicate a burnt or open valve and the leak test would have told him not only a valve was leaking, but it would also tell him which valve [ int/exh]..that is why we do a leak test right after a compression test. Narrow down the diagnosis right then and there..........
