What are the pros/cons of my adult son being on both his employer's plan and on our plan? (U.S.)

Our insurance, a good but not great plan, is via my wife's employment. My 22yr old son is starting his first job out of college, and the employer's somewhat better insurance plan would be relatively inexpensive for him. We will not save any money by taking him off our plan, until he and our daughter, 20 and still in school, can both come off. Wife's HR said it may benefit us for him to get on his employer's plan, as primary, and stay on her plan, as secondary. What are the pros/cons of such an arrangement, and are there any unexpected "gotchas" we should know about?
