I know what it SAYS on the paperwork (I've got three of those tanks and the letters) but I suspect its a CYA move since PST isn't the actual manufacturer of the valves.
If it bothers you, tear them down or have them O2-cleaned. I took a peek and didn't see anything I didn't like - and I PP fill mine.
