There is nothing in the 22nd Amendment about whether the terms are consecutive or not.
No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once...

The author can't spell and can't add. Somehow he added two four year terms and came up with ten years as the total.
...which limits presidents to two consecutive terms or ten years in office.
