No, the text is correct because of the ellipsis. See response from Peter.

An interrupt condition is *never* recognized "during generation of [an] address." An addressing exception or a protection exception may be recognized subsequently when that address is used to access storage. And that is unrelated to whether a carry out of the high-order bit position occurred. Address generation and storage access are two different topics. They should be discussed separately.
