Multiple actions in a single button/link?

I came across this today while reviewing a mock from a coworker on another project, I told him it was "definitely wrong" but couldn't find any supporting UX guidelines that tackle this exact issue.

These were the options below a standard web form to add a user. Aside from the labels being incorrect, the button with TWO actions seems clearly wrong. If you have any best practice/guideline links this conflicts with it would be much appreciated.
