This sentence of the rules implies, that in all other cases, where routed figures are forced to move, they must be eliminated.
This is bad logic. The rules say that this is an exception to the rule. You cannot conclude that all other cases are ruled exactly the same and cannot have an exception. (As mentioned by Scott, there are other cases where routed units can move, although it is not the "regular" case)
