Microsoft buys Groove: New York Times gets a significant fact wrong?

Scoble (and everyone else) comments:

"We bought Groove and made Ray Ozzie our CTO."

Except, according to the New York Times:

"Mr. Ozzie will join Microsoft's two other chief technical officers, David Vaskevitch and Craig Mundie"

Interesting definition of "Chief". I wonder whether the New York Times got it wrong?
