Sad thing is, these are probably being used by him to repair 50 year old brake lines with single pot master cylinders.. Steel compression fittings are not that new, but are only legal for brake line repairs in a few states. There legal in NY, but I wouldn't do it, even if they were cheap enough. CT obviously not 1 of the legal states given the pdf above.

Yes, they are! Simple as that and you need to quit posting misleading information as many don't know the difference. They may work, but they are still illegal in most states. If it's a compression fitting, it's illegal until the regulations are lifted.
