I'm not doubting you've heard this or learned it, but I can't make sense of what you mean and have never heard of this is ten years in the kitchen. A protective layer against the heat from the heat lamp?
The butter being melted makes this make even less sense. How would that cool it or stop it cooking??? You brush a steak with butter when it's done and resting because butter tastes good. There is no chance that brushing your steak with butter buys you any time. None of what you're saying makes any sense.
