Speechwriter does all the work, takes all the responsibility, gets none of the credit

From a job ad I saw for an executive speechwriter for the Federal Reserve Bank of Atlanta:

“This role involves crafting clear and impactful speeches, drawing on subject matter experts to draft remarks delivered by the President and First Vice President. These remarks convey the Bank’s essential views on public policy.”

So far so good. But then the next line:

“While the words are the product of the speaker, the speech writer is responsible for the substance and quality of the content.”

Shouldn’t it be more like the other way around?
