This almost sounds like the idea of cooking a puerh to simulate aging, and then letting it age naturally. Perhaps the sealing somehow helps the aging process fastest, and then the ceramic helps with unpleasant odors, which makes sense to me given the nature of ceramics and the usual shapes of the jars.
It's exactly the opposite of the ripening process for shu pu'er. That's basically controlled composting over a short, defined period of time... giving the tea a lot of moisture / humidity, and covering it with blankets.... artificially simulating the natural aging process.
This is more like providing a normal storage environment, which will make the tea age, undisturbed, very slowly, since there will only be a little bit of oxygen, hopefully very little humidity (with a less roasted tea, putting dessicants in the storage container might be a good idea too), and no circulation of new air. It doesn't accelerate the aging, just makes it harder for sourness and such to develop, and means that you can age the tea longer without re-roasting.
For a high-fired Da Hong Pao, I wouldn't think you'd need to be as careful about storage as with Dancong, (I've heard of people aging high-fired yan cha in paper bags or other not-that-well-sealed containers), but the places in Wuyishan I've seen do seem to age their yan cha in pretty well sealed containers. As far as I've seen, which is pretty limited, they seem to use those old school lead / tin containers with a small top opening and a double-lid.
I personally like to hedge my bets a little, and try using different types of containers to see what works and what doesn't.
The modern cheap stainless-steel type canisters never seem to be super well sealed to me, and they seem to impart a slight metallic taste to the tea... I have had better luck with various types of ceramic canisters.

That should work provided the vendor's bags are thick and don't smell bad, and that they're not vacuum sealed. While tea that's aging shouldn't have much extra room in the container, it also shouldn't be a complete vacuum.
