They may not think about it that way, but if one of that couple got a promotion from the other then every other person on the team pretty much has grounds for a law suit. There are reasons these rules exist, and the CEO of a high profile company has no excuse not to know them all.

Extremely rare (winning such a lawsuit). Prior to these kinds of rules becoming the norm, how often did anyone win such a lawsuit? It's a rounding error close to 0.
There are plenty of publicized cases where one party openly stated she got promotions because of her affair with a senior. No lawsuits were even filed in the ones I know.
I'm in favor of such rules precisely because it's hard to win such a suit.
She was a direct report of the CEO. There are no promotions possible. She was max level already.
