Ah, that would make sense.
I actually thought the most likely intended meaning was that an algorithm in O(a^n) must take asymptotically longer than one in O(b^n) as n goes to infinity (if a > b), which isn't true. (For example, when a > b, then every algorithm in O(b^n) is also in O(a^n), but obviously no algorithm can asymptotically require more time than itself.)
