That's convenient. The organizations assert that they can tell certified persons what's allowed and not, but if the certified person follows all the rules and something still goes sideways, the license ends up being worthless, because they can't say, "I did it this way because that's what the standards I'm required to adhere to say"?
As a programmer (who gets titled "software engineer" whether I liked it or not) this is terrible. What incentive would I have for getting a license if it doesn't protect me from liability?
When you give your stamp of approval on a project then you're legally liable for it.
You can be sued for incompetence. Then, you have to go to court and defend yourself. Or, more commonly, your company will send a lawyer but you still may be called to testify.
